Safe driving: following distance, weather and skids: Texas DPS written test practice
Rules to understand before practicing
Keep a following gap that gives you time to react, and increase it when grip or visibility is poor. Scan ahead and check mirrors and blind spots before changing direction. On a wet road, sudden braking or steering can cause loss of control. Use low beams in fog; high beams reflect light back toward you. A common mistake is relying entirely on mirrors or a driver-assistance feature. You still need to observe the road and remain ready to act.

Explanation: When it's raining, use your low beams—they provide better visibility and don't cause unnecessary glare; parking lights alone aren't enough.
14. If your car starts to hydroplane (slide on a film of water), you should:
Brake hard
✓ Ease off the gas smoothly, without braking abruptly or jerking the steering wheel
Turn the steering wheel sharply to one side
Shift into neutral right away
Explanation: If you start to hydroplane, gently ease off the gas and keep the steering wheel straight, avoiding sudden braking and sharp turns until the tires regain traction.
17. Your vehicle begins to hydroplane (skid on a film of water) at speed. You should:
Brake hard immediately
Turn the steering wheel sharply to regain control
✓ Ease off the gas and steer straight until the tires regain traction
Accelerate to drive through the water faster
Explanation: Hard braking or sharp steering can make a skid worse. Ease off the accelerator and keep the wheels pointed straight until traction returns.
19. Fatigue while driving is especially dangerous because it:
Has no effect on the driver's reaction time
✓ Slows reaction time and can cause a brief microsleep while driving
Affects only passengers
Is dangerous only at night
Explanation: Fatigue slows reaction time and increases the risk of “microsleep”—a brief, involuntary lapse into sleep while driving, which is enough to cause an accident.
20. If you are driving on the highway slower than the flow of traffic, you should:
Stay in any lane of your choice
✓ Keep to the right, yielding the left lanes to faster traffic
Drive strictly in the left lane
Constantly change lanes, looking for an open one
Explanation: Slower traffic must keep to the right and yield the left lanes to faster vehicles—a specific requirement of the Texas Transportation Code.
