1. Environmental & Public Health Hazards are Real

Environmental concerns have been a popular subject of debate as of recently. With our natural surroundings increasingly enforcing its own reparations on all people globally. The time for change is now and far too many people disregard it as if it's a folktale and not a scientific fact. Even worse, those who understand the detrimental effects of emissions and air pollutants on the environment are unaware how to take preventative or proactive measures. 

2. Improving Air Quality & The Environment

The federal government has many programs in place to protect the environment. Currently,  the dangerous toxins effecting our global air quality and the ozone are considered a public health hazard. The Environmental Protection Agency (EPA) and the Air Resources Board (CARB or ARB) are two of the most effective programs put into place to protect and improve the quality by reducing harmful elements affecting both humans and air quality. 

3. Diesel Particulate Filters are Required for Trucks

In 2007 the EPA mandated a law that has greatly impacted the moving industry. This is specifically because many moving businesses necessitate heavy-duty diesel engine trucks to haul freight or household goods. Ten years ago emission standards and regulations were set for all diesel engine vehicles and trucks. It was discovered that diesel emissions exhaust emit large amounts of toxins such as soot, ash, particulate matter, and many other harmful emissions into the air. 

To reduce harmful emissions, regulations stated that a diesel particulate filter (DPF) must be fitted for every diesel truck and even vehicles. A DPF is a filter that is designed to work with the emissions system and catch the soot, ash, and PM, therefore cleaning a trucks exhaust. This component or part has since been regulated and enforced through many different means.

If caught without a DPF fitted, heavy fines were and still are given, set emission standards must be met and can be checked when stopping at weigh stations or truck stops, and other requirements that have developed since. Many enforcement strategies involve large fines on top of repairs, replacements, or installations. 

4. Compliance is Crucial - You WILL Get Fined

Being compliant is the most significant aspect of protecting your business from large fines from the USDOT, the EPA, and ARB, especially if you encounter a surprise audit. The laws and regulations of the industry are constantly being updated, so it is vital that you stay informed of these briefings. This is considered your job as a business owner to keep track of such modifications and stay up to date. Be careful to check regulations if moving from coast to coast especially. For example, California is one of the most strict states regarding emissions control enforcement. Once entering California, your diesel truck must abide by CARB's state regulations to avoid fines. 

It is also an important factor to keep in mind that consumers who are renting moving trucks with diesel engines are either aware of these conditions or the rental companies fleets are all in complete compliance with the law.  

5. Fundamental Programs

Since the 60's, the air quality has drastically improved and has become a substantial field of study. Areas of high air pollution, such as those that are heavily urbanized have become vulnerable points of a question.

Two particular programs are fundamental in their determination to protect human and environmental health: the Clean Air Act and California's Smog Check Program. Utilizing advanced technology, the moving industry has resulted in critical benefits. Advancements in areas protecting air quality and the environment are critical, not only for our generation but for those to come as well.

6. Regulation Compliance

According to some new air quality rules or 'Heavy-Duty Vehicle Greenhouse Gas Emission Reduction Regulations' commercial truck usage and maintenance systems will be required. The 'On Road Heavy Duty Diesel Vehicle (In-Use) Regulation' or the Truck and Bus Regulation, proceedings were validated and sanctioned by the Air Resources Board (ARB). 

The regulation was put into place in 2008, giving trucks 3 years to meet the start date performance requirements between 2011 and 2023. By the year 2023, all vehicles must have at least a 2010 model of engine or at least the equivalent. Even heavy-duty vehicles with gross weight vehicles that are 14,000 pounds or greater (GVWR) that operate in or out of state are certified to regulations.

For any moving companies who are starting a business, this is a crucial element to factor into your fleets or trucks if you plan on using diesel engine powered systems. 

7. Smoke Checks

The Air Resources Board (ARB) is authorized to test any and all heavy-duty truck for excessive smoke and tampering. This is essentially a smog check that includes CA vehicles, out-of-state, and even Mexican and Canadian vehicles. They are likely performing these tests by the CHP at weigh stations, fleet locations, and other randomly selected areas.

Much like being audited by USDOT agents, an inspection team or CHP can select any vehicle for testing and direct it into a special lane. They block the wheels for safety and use a snap-acceleration testing method. This includes recording RPMs, which catalogs the RPM at idle and max allowable speeds.

8. The Snap-Acceleration Test Explained

The Snap-Acceleration Test allows for the inspector to situate a smoke meter just above or in the exhaust pipe. Once positioned, the driver must rev the engine rapidly three times while in neutral gear. This is to clear the exhaust of loose particles. this snap-acceleration test three times. This gauges how clear and clean the smoke emissions are. 

9. Visual Inspection

Lastly, there is the Visual Inspection, in which the inspector checks under the vehicle's hood for any conspicuous indications of tampers. Also, this help to record data regarding the engine and to confirm that the vehicle has the correct emission control label.

10. Fines, Fines, & More Fines 

These regulations are not something to take lightly. Reparations start at $800 for the first violation in addition to any repairs the truck may need. However, if the truck is repaired with the 45 day grace period, the ARB will defer $500 off of the fine.

Consequently, if the regulations are not met within the 45 given days, the full fine of $800 must be paid along with the reparation of the truck. If the penalty fine and the repair continue with the year, the fine spikes to repairs, an $1800 fine, and the truck must be retested for compliance with ARB.

In circumstantial situations, CHP officers even have the option to revoke your vehicle from service for any unpaid citations or if the vehicle was never repaired. Even further, the DMV can hold registration renewal until the fine is settled.

These fines will vary based on state, so it is important to be aware of what state you're entering, leaving, or traveling locally. This goes for moving companies and their businesses moving interstate performing state to state moves as well as those renting diesel trucks to consumers for relocation purposes.

11. The Periodic Smoke Inspection Program (PSIP)

Another standard regulation that is now in effect is the Periodic Smoke Inspection Program (PSIP) which also is directed specifically towards heavy-duty diesel trucks that are based in California. However, this is different in two ways, the first being that it applies to fleets with two or more heavy-duty diesel-fueled vehicles with a GVWR of 6,000 pounds minimum or more. If the above qualifies for you, you must meet the regulations below:

  • vehicles must have an annual test with a passing smoke opacity meter  PRIOR  to December 31st of each year
  • Vehicles must pass smoke opacity regulations 
  • If any of the vehicles are found to be non-compliant, they must make the repair immediately to meet regulations
  • Vehicles must keep records of the following: opacity tests, repair information, post-repair results all for a minimum of the previous 2 years

12. Idling Limit Regulations for Trucks 

This is the easiest and most comprehensive law enforced. It simply states that the maximum minutes of time that a heavy-duty diesel powered truck can idle is at maximum five minutes. This is due to the diesel fuel emissions that are not burned off while idling or even driving (such as stop and go traffic). This law was implemented with the idea that this would reduce the particulate matter (PM). It is important to note that when in a school zone (this applies to buses mostly) the idling time is reduced even less.

13. The Importance of Compliance

Not only are they good for your truck, they are good for you health, others health, the well-being of the environment and are generally enforced, not because these agencies purely want to fine you. They simply want to improve the quality of life that surrounds us, which is something that is necessary right now. However, it is important for those in the moving industry to be aware of these federal and state regulations in order to remain compliant when performing interstate or local moves.

Did You Know


The trucking industry has made a large historical impact since the early 20th century. It has affected the U.S. both politically as well as economically since the notion has begun. Previous to the invention of automobiles, most freight was moved by train or horse-drawn carriage. Trucks were first exclusively used by the military during World War I.
After the war, construction of paved roads increased. As a result, trucking began to achieve significant popularity by the 1930's. Soon after trucking became subject to various government regulation, such as the hours of service. During the later 1950's and 1960's, trucking accelerated due to the construction of the Interstate Highway System. The Interstate Highway System is an extensive network of freeways linking major cities cross country.

Question Alongside the many different trailers provided are motorcycle trailers. They are designed to haul motorcycles behind an automobile or truck. Depending on size and capability, some trailer may be able to carry several motorcycles or perhaps just one. They specifically designed this trailer to meet the needs of motorcyclists. They carry motorcycles, have ramps, and include tie-downs. There may be a utility trailer adapted permanently or occasionally to haul one or more motorcycles.

Question In many countries, driving a truck requires a special driving license. The requirements and limitations vary with each different jurisdiction.

Question The decade of the 70s saw the heyday of truck driving, and the dramatic rise in the popularity of "trucker culture". Truck drivers were romanticized as modern-day cowboys and outlaws (and this stereotype persists even today). This was due in part to their use of citizens' band (CB) radio to relay information to each other regarding the locations of police officers and transportation authorities. Plaid shirts, trucker hats, CB radios, and using CB slang were popular not just with drivers but among the general public.

Question “ The first original song about truck driving appeared in 1939 when Cliff Bruner and His Boys recorded Ted Daffan's "Truck Driver's Blues," a song explicitly marketed to roadside cafe owners who were installing juke boxes in record numbers to serve truckers and other motorists.” - Shane Hamilton

Question According to the U.S. Census Bureau, 40 million United States citizens have moved annually over the last decade. Of those people who have moved in the United States, 84.5% of them have moved within their own state, 12.5% have moved to another state, and 2.3% have moved to another country.

Question The moving industry in the United States was deregulated with the Household Goods Transportation Act of 1980. This act allowed interstate movers to issue binding or fixed estimates for the first time. Doing so opened the door to hundreds of new moving companies to enter the industry. This led to an increase in competition and soon movers were no longer competing on services but on price. As competition drove prices lower and decreased what were already slim profit margins, "rogue" movers began hijacking personal property as part of a new scam. The Federal Motor Carrier Safety Administration (FMCSA) enforces Federal consumer protection regulations related to the interstate shipment of household goods (i.e., household moves that cross State lines). FMCSA has held this responsibility since 1999, and the Department of Transportation has held this responsibility since 1995 (the Interstate Commerce Commission held this authority prior to its termination in 1995).

Question AMSA wanted to help consumers avoid untrustworthy or illegitimate movers. In January 2008, AMSA created the ProMover certification program for its members. As a member, you must have federal interstate operating authority. Members are also required to pass an annual criminal back check, be licensed by the FMCSA, and agree to abide by ethical standards. This would include honesty in advertising and in business transaction with customers. Each must also sign a contract committing to adhere to applicable Surface Transportation Board and FMCSA regulations. AMSA also takes into consideration and examines ownership. They are very strict, registration with state corporation commissions. This means that the mover must maintain at least a satisfactory rating with the Better Business Bureau (BBB). As one can imagine, those that pass are authorized to display the ProMove logo on the websites and in marketing materials. However, those that fail will be expelled from the program (and AMSA) if they cannot correct discrepancies during probation.

Question A business route (occasionally city route) in the United States and Canada is a short special route connected to a parent numbered highway at its beginning, then routed through the central business district of a nearby city or town, and finally reconnecting with the same parent numbered highway again at its end.

Question As of January 1, 2000, the Federal Motor Carrier Safety Administration (FMCSA) was established as its own separate administration within the U.S. Department of Transportation. This came about under the "Motor Carrier Safety Improvement Act of 1999". The FMCSA is based in Washington, D.C., employing more than 1,000 people throughout all 50 States, including in the District of Columbia. Their staff dedicates themselves to the improvement of safety among commercial motor vehicles (CMV) and to saving lives.


Truckload shipping is the movement of large amounts of cargo. In general, they move amounts necessary to fill an entire semi-trailer or inter-modal container. A truckload carrier is a trucking company that generally contracts an entire trailer-load to a single customer. This is quite the opposite of a Less than Truckload (LTL) freight services. Less than Truckload shipping services generally mix freight from several customers in each trailer. An advantage Full Truckload shipping carriers have over Less than Truckload carrier services is that the freight isn't handled during the trip. Yet, in an LTL shipment, goods will generally be transported on several different trailers.


In the moving industry, transportation logistics management is incredibly important. Essentially, it is the management that implements and controls efficiency, the flow of storage of goods, as well as services. This includes related information between the point of origin and the point of consumption to meet customer's specifications. Logistics is quite complex but can be modeled, analyzed, visualized, and optimized by simulation software. Generally, the goal of transportation logistics management is to reduce or cut the use of such resources. A professional working in the field of moving logistics management is called a logistician.

Question In 1991 the film "Thelma & Louise" premiered, rapidly becoming a well known movie. Throughout the movie, a dirty and abrasive truck driver harasses the two women during chance encounters. Author Michael Dunne describes this minor character as "fat and ignorant" and "a lustful fool blinded by a delusion of male superiority". Thelma and Louise exact their revenge by feigning interest in him and then blowing up his tanker truck full of gas.

Question The feature film "Joy Ride" premiered in 2001, portraying the story of two college-age brothers who by a CB radio while taking a road trip. Although the plot seems lighthearted, it takes a quick turn after one of the brothers attempts a prank on an unknown truck driver. They soon find out the dangerous intentions of this killer driver, who is set on getting his revenge. Seven years later in 2008 the sequel "Joy Ride 2: Dead Ahead" came out on DVD only. Similar to its predecessor, the plot involves another murdering truck driver, a.k.a "Rusty Nail". He essentially plays psychological mind games with a young couple on a road trip.

Question In order to load or unload bots and other cargo to and from a trailer, trailer winches are designed for this purpose. They consist of a ratchet mechanism and cable. The handle on the ratchet mechanism is then turned to tighten or loosen the tension on the winch cable. Trailer winches vary, some are manual while others are motorized. Trailer winches are most typically found on the front of the trailer by towing an A-frame.

Question Ultra light trucks are very easy to spot or acknowledge if you are paying attention. They are often produced variously such as golf cars, for instance, it has internal combustion or a battery electric drive. They usually for off-highway use on estates, golf courses, parks, in stores, or even someone in an electric wheelchair. While clearly not suitable for highway usage, some variations may be licensed as slow speed vehicles. The catch is that they may on operate on streets, usually a body variation of a neighborhood electric vehicle. A few manufacturers produce specialized chassis for this type of vehicle. Meanwhile, Zap Motors markets a version of the xebra electric tricycle. Which, believe it or not, is able to attain a general license in the United States as a motorcycle.

Question A Ministry of Transport (or) Transportation is responsible for transportation within a country. Administration usually falls upon the Minister for Transport. The term may also be applied to the departments or other government agencies administering transport in a nation who do not use ministers. There are various and vast responsibilities for agencies to oversee such as road safety. Others may include civil aviation, maritime transport, rail transport and so on. They continue to develop government transportation policy and organize public transit. All while trying to maintain and construct infrastructural projects. Some ministries have additional responsibilities in related policy areas as mentioned above.

Question The industry intends to both consumers as well as moving companies, this is why there are Ministers of Transportation in the industry. They are there to set and maintain laws and regulations in place to create a safer environment. It offers its members professional service training and states the time that movers have been in existence. It also provides them with federal government representation and statistical industry reporting. Additionally, there are arbitration services for lost or damaged claims, publications, public relations, and annual tariff updates and awards. This site includes articles as well that give some direction, a quarterly data summary, and industry trends.

Question There are various versions of a moving scam, but it basically begins with a prospective client. Then the client starts to contact a moving company to request a cost estimate. In today's market, unfortunately, this often happens online or via phone calls. So essentially a customer is contacting them for a quote when the moving company may not have a license. These moving sales people are salesman prone to quoting sometimes low. Even though usually reasonable prices with no room for the movers to provide a quality service if it is a broker.

Question Words have always had a different meaning or have been used interchangeably with others across all cultures. In the United States, Canada, and the Philippines the word "truck" is mostly reserved for larger vehicles. Although in Australia, New Zealand, and South Africa, the word "truck" is generally reserved for large vehicles. In Australia and New Zealand, a pickup truck is usually called a ute, short for "utility". While over in South Africa it is called a bakkie (Afrikaans: "small open container"). The United Kingdom, India, Malaysia, Singapore, Ireland, and Hong Kong use the "lorry" instead of truck, but only for medium and heavy types.
