1 . When in heavy traffic, the safest driving speed is:

Slower than the speed being driven by surrounding traffic.

The same speed being driven by surrounding traffic.

Faster than the speed being driven by surrounding traffic.

In heavy traffic, it is safest to travel at the same speed as other vehicles. If two vehicles continue to drive in the same direction at the same speed, they cannot hit each other.

2 . Before operating a tank, a driver should:

Remove the rear shut-off valve.

Check vapor recovery kits, if applicable.

Remove a third of their fuel.

When inspecting your tank vehicle before operation, make sure all specialty equipment is in safe working condition. This includes vapor recovery kits, grounding and bonding cables, and emergency shut-off systems.

3 . When should mirrors be adjusted?

Before driving

While driving

After driving

The adjustment of your mirrors should be checked prior to the start of all trips. Adjust your mirrors as needed.

4 . Hydroplaning usually occurs:

When tires are properly inflated.

When driving at speeds slower than 15 mph.

In areas where water collects on the road.

Hydroplaning occurs on surfaces where water has collected. If there is enough water, vehicles can hydroplane at speeds as low as 30 mph. Hydroplaning becomes more likely if tires are under-inflated or if the tread is worn.

5 . When traction is poor, a driver should accelerate especially slowly:

Because it is always good to accelerate slowly.

To keep from losing control of the vehicle.

To keep from accelerating faster than the vehicle ahead.

You should accelerate very gradually when driving under slippery conditions. Using too much power in such conditions may cause you to lose control of your vehicle.

6 . How much water must be present for a vehicle to hydroplane?

Usually several inches

A good amount, such as a large puddle

A small amount

Hydroplaning is an effect in which a vehicle's tires lose traction with the surface of the road and instead glide along a layer of water. There does not have to be much water on the road for this to occur.

7 . Before a trip, you can make sure air flows to all trailers by:

Checking for moving air inside of each trailer.

Listening for air at the rear shut-off valve.

Feeling for air at the front shut-off valve.

Before a trip, ensure that air in the air brake system reaches all trailers. Do this by waiting for air pressure to build, then sending air to both the emergency and service lines and opening the shut-off valves on the rear of the last trailer. If air escapes from the shut-off valves in the rear of the combination, the air is being supplied to the entire vehicle.
