Texas CDL — General Knowledge: Sharing the Road Practice Test

Question 1

Drivers of recreational vehicles and rented trucks call for extra caution because they:

Accepted Answer

Often lack professional skill and are easily shoved by turbulence — Their experience varies enormously and few have professional training. Smaller vehicles pulling trailers are also easily shoved around by the turbulence off a big rig, so cut your speed, leave room, and pass as far to the left as is safe.

Answer

Are barred by law from using interstate highways

Answer

Always travel below the posted minimum speed

Answer

Need a longer stopping distance than a loaded tractor-trailer

Question 2

Before you start across railroad tracks, you must be sure that:

Accepted Answer

You have room to drive completely across without having to stop — Never start across the tracks unless you have enough room to get completely across without stopping. Do not let traffic ahead trap your vehicle on the tracks.

Answer

You can stop halfway to look for trains

Answer

There is a vehicle stopped just past the tracks to follow

Answer

You can beat the train if you hurry

Question 3

Which vehicles must stop at every railroad crossing, even when no train is in sight?

Accepted Answer

Buses carrying passengers and vehicles hauling placarded hazardous materials — Buses carrying passengers and vehicles hauling placarded hazardous materials must stop at railroad crossings. Most other commercial vehicles slow, look, and listen but need not always stop.

Answer

Every commercial vehicle, at all times

Answer

Only empty flatbed trailers

Answer

No commercial vehicles ever need to stop

Question 4

How much clearance should you leave to the left of a motorcycle or bicycle you are overtaking?

Accepted Answer

At least six feet — Air moving around a large vehicle can drag a two-wheeler sideways by two or three feet, so leave a cushion of six feet or more on the left when you go past one.

Answer

Roughly two feet

Answer

A full lane width plus another ten feet

Answer

Whatever the shoulder happens to allow

Question 5

Oncoming traffic keeps you from moving over to get around a motorcycle ahead. You should:

Accepted Answer

Stay behind the rider at a safe speed until the way is clear — Never split the lane with a two-wheeled vehicle. If the next lane or the oncoming lane is not available, drop back and stay behind the rider at a safe speed until the way is clear.

Answer

Share the lane and slip by on the left half of it

Answer

Flash your headlights so the rider moves to the right

Answer

Go around using the shoulder

Question 6

After one train clears a multi-track crossing, before you proceed you should:

Accepted Answer

Make sure no second train is coming on another track before you cross — Look both ways again, because a second train may be coming on another track, sometimes hidden by the first. Cross only when you are sure all tracks are clear.

Answer

Move forward the instant the first train clears

Answer

Assume it is always safe once one train has passed

Answer

Back up to let other vehicles go first

Question 7

When crossing railroad tracks in a commercial vehicle, you should:

Accepted Answer

Cross in a low gear without changing gears — Do not change gears while you are on the tracks. Pick a gear that lets you cross without shifting, so you do not risk stalling on the tracks.

Answer

Shift to a higher gear halfway across

Answer

Stop with the trailer on the tracks to look around

Answer

Speed up and shift as you cross

Question 8

A big rig drives a wall of air along in front of itself. Because of that, when you pass a car you should:

Accepted Answer

Leave as much space between the two vehicles as you can — The air a big rig shoves ahead of itself can buffet a passenger vehicle. Leaving as much room as you can between the two vehicles keeps that push from unsettling the car you are going by.

Answer

Pass at the highest safe speed to shorten the effect

Answer

Stay close so the car gets pulled along behind you

Answer

Pass only where the road runs downhill

Question 9

When driving through a highway work zone, you should:

Accepted Answer

Slow down, obey the signs, and watch for workers — Slow down, obey the posted work-zone speed and signs, watch for workers and equipment, and be ready for sudden stops and narrowed lanes.

Answer

Keep your normal highway speed

Answer

Change lanes as often as you can

Answer

Follow the vehicle ahead very closely

Question 10

Texas guidance for a professional truck driver who meets a school bus is to:

Accepted Answer

Give it all the room you can and expect frequent stops for children — Give a school bus all the room you can. It will stop often to load and unload children, and its driver may have attention pulled away by the students aboard.

Answer

Get past it quickly before it reaches the next stop

Answer

Follow closely so cars cannot slot in between

Answer

Treat it exactly the way you would any other truck
