After too little sleep, you drift over lane lines and hit a rumble strip. What does this warn you about?
Correct answer: Possible drowsy-driving impairment
Lane drift and rumble-strip contact can signal drowsiness. Treat them as warnings, not reassurance that you can continue.

After little sleep, you drink coffee and feel more awake. Which conclusion is safest?
Correct answer: You may still have brief sleep episodes
Caffeine alone may not prevent brief sleep episodes in a sleep-deprived driver.

Where should you find the recommended tire pressure for your car?
Correct answer: The vehicle label or owner’s manual
Use the vehicle manufacturer’s recommendation, not the maximum molded on the tire.

What minimum time without driving does NHTSA use to define cold tires for a pressure check?
Correct answer: 3 hours
A three-hour rest lets you compare the reading with the recommended cold pressure.

A tire blows out at speed. Which response helps you retain control?

A barricade closes a flooded road, but a gap is wide enough for your car. What should you do?
Correct answer: Use another route; do not go around the barrier
Floodwater can hide a collapsed road. A gap beside a barricade is not permission to enter.
Source: Floodwater hazards — Never drive around barriers blocking a flooded road ↗
Floodwater covers the road ahead. Why is judging its safety from your seat unreliable?
Correct answer: Depth and road damage may be hidden
Avoid entering floodwater. Its appearance cannot establish a safe crossing or sound pavement underneath.

A snowplow is clearing the lane ahead. Which position should you avoid?
Correct answer: Traveling alongside the plow
Plows may overlap lanes, turn widely, or stop. Give them space instead of staying beside them.

Your stopped car is surrounded by snow. Before briefly running the engine for warmth, check that:
Correct answer: The exhaust pipe is clear of snow
Blocked exhaust can cause carbon monoxide poisoning. Run the engine only intermittently, not continuously with the windows closed.

You install rubber floor mats for wet weather. What safety check matters most?
Correct answer: They fit securely and cannot interfere with pedals
Use correctly sized mats and the manufacturer’s retention clips. Loose mats can obstruct braking or acceleration.

Strong gusts begin while cruise control is on. What does California DMV recommend?
Correct answer: Turn cruise control off
Keep direct control of the accelerator in high winds rather than relying on cruise control.
Source: Section 8 — High Winds ↗
Strong gusts begin pushing your car sideways. Which adjustment gives you better control?
Correct answer: Reduce speed and keep a firm grip on the steering wheel
Lower speed gives you more time to respond, and a firm grip helps resist unpredictable gusts. Turn cruise control off. If conditions become unsafe, pull over safely and wait.

On a cold, wet day, why should you be especially cautious at a bridge?
Correct answer: It may freeze before nearby roadway
Bridges and overpasses can become icy before the rest of the road. Do not assume nearby clear pavement guarantees traction.

In California, dim high beams when an oncoming vehicle is within:
Correct answer: 500 feet
Use low beams within 500 feet of approaching traffic to avoid glare.

You approach another vehicle from behind at night in California. Dim high beams within:
Correct answer: 300 feet
The following-vehicle distance is 300 feet, distinct from the 500-foot oncoming-traffic rule.

Which starting hand positions does DMV recommend for hand-to-hand (push/pull) steering?
Correct answer: 9 and 3, or 8 and 4 o’clock
These positions support push/pull steering without crossing your hands over the wheel’s center.

An important message arrives while you are driving alone. How should you handle it?
Correct answer: Park safely before reading or replying
If it cannot wait, leave traffic and park in a safe location first.
Source: Safe-driving tips — Park before reading or sending messages ↗
You have a passenger and need to respond to a message during a trip. What is the safer choice?
Correct answer: Ask the passenger to handle the message
A passenger can handle messages while you keep your attention on driving.

Under standard R2 controls, an AWD car with snow-tread tires on all four wheels is exempt from fitting chains. Must it carry traction devices?
Correct answer: Yes, even while exempt from fitting them
The R2 fitting exemption does not remove the carrying requirement. Follow checkpoint instructions.
Source: Chain Requirement Levels — Requirement 2 (R2) and carrying note ↗
Which vehicle is exempt from chains or traction devices under California R3 controls?
Correct answer: None
R3 requires traction devices on every vehicle, without an AWD or snow-tire exemption.
Source: Chain Requirement Levels — Requirement 3 (R3) ↗
Signs require chains. Where should you stop to install them?
Correct answer: Completely off the roadway to the right
Use a safe pull-off; installing chains in a traffic lane endangers you and blocks others.

You want to pass a motorcycle with your car. Should you squeeze past within the rider’s lane?
Correct answer: No; give the rider a full lane
Leave the rider room. California’s motorcycle lane-splitting rules do not invite cars to squeeze past riders.

A truck ahead signals right, then moves left as it approaches the corner. How should you respond?
Correct answer: Stay back; it may need the space to complete a wide right turn
A truck's rear wheels take a shorter path than its front wheels, so it may swing left before turning right. The opening beside it can disappear during the turn.

A lane is too narrow for a car and bicycle side by side. May the cyclist ride away from the right edge?
Correct answer: Yes, when the lane is too narrow to share safely
California’s keep-right rule has exceptions, including a lane too narrow for safe side-by-side travel.
