When you cargo tank has baffles, what handling effect do you expect?
- There will be less side-to-side surge than there is in tanks without baffles
** There will be less front-to-back surge than there is in tanks without baffles **
- There will be more slow surge than quick surge
If you are driving a tanker and need to steer quickly to avoid a hazard you:
- Will find that tankers are easier to countersteer than most vehicles
** Should not apply the brakes while turning **
- Should wrap your thumb around the steering wheel before starting the steering movement
Which of these is the best way to take a curve?
** Slow to the safe speed before entering, then accelerate slightly through the curve **
- Slow to a safe speed before entering, then coast through the curve
- Maintain speed until you enter, then brake as you drive through the curve
Hauling liquids in tankers require special care for two reasons. One reason is the ___________center of gravity
- Flat
- wide
** High **
Empty trucks
- Have better traction when stopping that full ones
** Requires greater stopping distance than full ones **
- Need less space ahead than full ones
An emergency forces you to stop your tanker or crash. You should:
- Use light pressure on the brake pedal
- Use only the emergency brake
*** Use only controlled or stab braking
Side to side surge can cause:
- Uneven tire wear
- Tire failure
** Roll over **
You should be extremely cautious when driving bore tanks, specially when you are:
- Going up and downhill
** starting or stopping **
- Loading and unloading
You are driving a tanker truck and the front wheels begin to skid. Which of these is most likely to occuer?
** You will continue in a straight line and keep moving forward no matter how much you steer **
- Liquid surge will pull the tank from the truck
- The truck will roll over
You are driving on a clear night. You must dim your headlights from high to low. You should adjust your speed so that you can sttop within
- 100 ft
- The distance you will travel in the next 15 seconds
** The distance you can see ahead **
You should know the outage needed for the liquids you are carrying because:- Some of the heaviest do not have any - Tank baffles are not always legal with outage *** Some liquids expand more than others when they get warm. ***when should the driver of a tanker that has lost its brakes use a truck escape ramp?- Only if the tank is empty *** Always *** - NeverBaffled liquid tanks have bulkheads:- That increase the amount of side to side surges - That separate the liquids from different areas of the tank *** With holes in them that let liquid flow through them ***If an oncoming vehicle drifts into your lane you should:- Use no less that one full turn of steering wheel to avoid it *** move to your right *** - Try to stop rather than turnIn NJ, A tank endorsment is required if your vehicleneeds a class A r B CDL and you want to haul a liquid or liquid gas in a tank or tanks having an individual rated capacity of more than 119 gallons and an aggregate rated capacity of 1000 gallons or moreBefore loading, unloading, or driving a tankerINSPECT THE VEHICLEOn all tank vehicle the most important item to check for isLEAKSDon't carry carry liquids or gases in aLEAKING TANKIt is a crimeTo carry liquid or gasses in a leaking tank.
