Correctly following the steps to couple and uncouple trailers is vital to safely operating a combination vehicle. After connecting the air lines to the trailer while coupling, you should supply air to the trailer.
Be sure to test the trailer emergency brakes before beginning a trip. After ensuring that the trailer rolls freely, you can test the emergency brakes by pulling out the trailer air supply control, or placing it in the "emergency" position. Pull forward slightly with the tractor and make sure the trailer does not move.
Backing is always dangerous because you cannot see everything behind your vehicle. Especially if you are unfamiliar with the area, you should get out of your vehicle and familiarize yourself with your path of travel before beginning to back up.
The National Response Center must be notified of any incident that results in death; hospitalization; $50,000 or more in estimated property damage; an evacuation of the general public or closure of a major transportation route/facility for more then one hour; fire, breakage, spillage, or suspected contamination involving radiation, bacteria, or toxins. Additionally, if the carrier judges the situation to be so serious that it should be reported, it should be reported.
Reduce your speed when traveling on surfaces that provide reduced traction. Reduce your speed by about one-third when driving on a wet road.
The purpose of an Anti-Lock Braking System (ABS) is to prevent a vehicle's wheels from locking up when the driver brakes hard on a slippery surface.
Rollovers can happen when a combination vehicle is turned too quickly. To help prevent the risk of rollover, it is important to keep the vehicle's center of gravity low by loading cargo as close to the ground as possible.
If you encounter an aggressive driver, you should not let yourself be provoked by any angry gestures they make toward you. Avoid making eye contact with the other driver and do not try to race them.
When positioning trailers in a combination, the most heavily-loaded trailer should be the closest to the tractor. The lightest trailer should be positioned in the rear.
Driving tanks requires special care because they usually have high centers of gravity. The driver should also expect cargo movement in transit, if transporting liquid cargo.
A leaking exhaust system can introduce carbon monoxide, which is poisonous, into the cab or sleeper berth.
Railroad-highway crossings may be difficult to cross when pulling a trailer with a low underneath clearance. In particular, both low-slung units and single-axle tractors pulling long trailers are especially challenging to drive over raised crossings.
When driving in reverse, it is always recommended that a driver backs their vehicle toward its left side. This will allow the driver the best possible view of the rear of their vehicle.
For the first step of a vehicle inspection, you should review the last inspection report on your vehicle, if there is one. The carrier should have repaired any problems noted on the report.
When turning quickly to avoid an object, turn only as much as is necessary to clear it. Do not apply the brakes while turning.
If you discover that a cargo of hazardous materials is leaking from your vehicle, you should park the vehicle as soon as possible. The longer you continue driving, the longer the trail of contamination becomes. While this creates potential danger and harm to others, it also increases clean-up expenses.
Landing gear, or trailer supports, should always be completely raised before a vehicle is driven. Landing gear that is not entirely raised could catch on railroad tracks or other hazards on the roadway.
The best thing to do when confronted with an aggressive driver is to get out of their way, if possible. Avoid making eye contact, which could further provoke the driver. Ignore any hand gestures made by the driver.
