Release the parking brake only when you have applied enough engine power to keep you from rolling back. on tractor trailer equipped with a trailer brake hand valve. the hand valve can keep you from rolling back. Speed up smoothly and gradually so the vehicle does not jerk. Rough acceleration can cause mechanical damage. When pulling a trailer rough acceleration can damage the coupling.
You should let air out of hot tires so the pressure goes back to normal
False Before driving check the mounting and air pressure inspect the tires every two hours or every 100 miles while driving in hot weather. Air temperature rises.DO Not Let the air out of tires because the tires will be too low so when temperature goes back to normal if tire is too hot stop and the go when the tire cools off or back to normal. Otherwise the tire may blow out or catch fire.
You should use your low beams whenever you can

Describe the proper breaking technique when going down along steep downgrade.
Remember the use of brakes on a long and or steep down grade is only a supplement to the braking effect of the engine. Once it is in the proper low gear the following are the breaking techniques. Apply the brakes just hard enough to feel a definite slowdown. When your speed has been reduced to approx five mph below your safe speed release the brakes.When your speed has increased to your safe speed repeat step one and two FOR EXAMPLE IF YOUR SAFE SPEED IS 40 MPH YOU WOULD NOT APPLY THE BREAKS UNTIL IT REACHES 40 AND KNOW YOU APPLY THE BRAKES HARD ENOUGH TO GRADUALLY REDUCE YOUR SPEED TO 35 MPH AND THEN RELEASE THE BRAKES. REPEAT THIS OFTEN UNTIL YOU REACHED THE END OF THE DOWNGRADE.
BEFORE STARTING DOWN HILL
SLOW DOWN AND SHIFT DOWN A SPEED SO THAT YOU CAN CONTROL WITHOUT USING THE BRAKE HARD. Otherwise the brakes can overheat and lose their braking power.
What factors determine your selection of a safe speed when going down a long steep downgrade.
Select the right gear before starting down the grade. Shift the transmission to a low gear before starting down the grade . Do not try to downshift after your speed has already been built up. You will not be able to shift into allow gear with older trucks a good rule is to for choosing gears use the same gear going down the hill is when you started up the hill. New trucks have low friction parts and streamlined shapes for fuel economy they also have more powerful engines That means they can go up higher hills in higher gears and have less friction and air drag going downa hill that would require to go up the hill Modern drivers may have to use lower gears going down a hill than would required to go up the hill . You should know what is good for your vehicle.
what are some things to do at an accident scene to prevent another accident.at the same spot

curves while turning and DOWN SHIFTING

IF THIS HAPPENS MAY SKID OUT OF CONTROL#2 DO NOT TURN AS NEEDED TO CLEAR WHATS EVER IN YOUR WAY. THE MORE SHARPLY YOU TURN THE GREATER THE CHANCE OF A SKID OR ROLLOVER.#3 BE PREPARED TO COUNTER STEER THAT IS TO TURN THE WHEEL THE OTHER DIRECTION,ONCE EVERYTHING IS CLEARED IN YOU PATH. UNLESS YOU ARE PREPARED TO COUNTER STEER, YOU WILL NOT BE ABLE TO DO IT QUICKLY ENOUGH. YOU SHOULD THINK OF EMERGENCY STEERING AS TWO PARTS OF ONE DRIVING ACTION. if ONCOMING DRIVER HAS DRIFTED TO YOUR LANE MOVE TO THE RIGHT LANE. THEN TURN INTO YOUR LANE.if something is in your way, the best way is to depending on the situation if have to in an emergency you will know by using your mirrors. if shoulder is clear going to the right is the best way ad at least your not going to ahead on collision. In some emergency's you may have to drive off the road.DO NOT TRY TO EDGE GRADUALLY BACK TO THE ROAD IF YOU DO YOUR TIRES MIGHT GRAB UNEXPECTEDLY AND YOU COULD LOOSE CONTROL .when BOTH TIRES ARE ON THE PAVED SURFACE COUNTER STEER IMMEDIATELY. the TWO TURNS SHOULD MAKE AS A SINGLE COUNTER STEER.

Gently put on the brakes, this presses linings against brake drums or discs and keeps mud, sit ,sand and water from getting in while driving through water.
