Hazard Perception, Emergency Maneuvers & Skid Control
16 free questions, part of the General Knowledge CDL practice test
Hazard perception and emergency maneuvers cover spotting trouble before it becomes an emergency, placing warning triangles correctly, and reacting when something goes wrong, braking, steering around an obstacle, or recovering from a skid. This section pulls from the CDL manual's controlled braking, stab braking, and skid correction guidance, plus the federal rules on triangle placement.

Where do you place warning triangles on a two-way or undivided highway?
One within 10 feet of the vehicle to mark its location, and the other two at 100 feet ahead and 100 feet behind it.
What are the four causes of a skid?
Over-braking, over-steering, over-acceleration, and driving too fast for conditions. All four come down to asking more traction from the tires than the road can give.
What do you do if your wheels lock up during stab braking?
Release the brakes completely, wait for the wheels to start rolling again, then reapply the brakes fully. Don't just ease off partway.
