Rain has made the road slippery. How should you adjust the gap behind the vehicle ahead?
Correct answer: Leave a larger gap than on dry pavement
Slippery pavement reduces tire grip, so you may need more distance to stop. A larger following gap and lower speed give you room to respond if the vehicle ahead brakes.

A wet curve is ahead. Why should you reduce speed before entering it?
Correct answer: Too much speed can exceed the tires' grip in the curve
Slippery pavement reduces traction. Entering more slowly helps prevent a skid and avoids needing sudden braking while turning. Steer smoothly and keep your speed safe throughout the curve.

How many seconds ahead is the minimum scanning distance recommended by the California handbook?
Correct answer: 10 seconds
Scan at least 10 seconds ahead while keeping your eyes moving. Looking beyond the vehicle immediately in front helps you spot developing hazards early and avoid last-minute braking or lane changes.

What basic rule helps maintain a safe following distance in normal conditions?
Correct answer: The three-second rule
Use at least the three-second rule and create more space when conditions are poor.

A driver is following too closely on a multilane road. What should you do?
Correct answer: Maintain control and move right when safe to let the driver pass
A tailgater has little room to stop. Avoid sudden moves and let the driver pass safely. Keep extra space ahead so you have more time to respond to slowing traffic.

What does California’s Basic Speed Law require?
Correct answer: Never drive faster than is safe for current conditions
The posted limit is not permission to drive faster than conditions safely allow.

With visibility limited to 100 feet in heavy rain or snow, above what speed does the handbook warn driving is unsafe, even though conditions may require much less?
Correct answer: 30 mph
The handbook warns that speeds above 30 mph are unsafe with only 100 feet of visibility in heavy rain or snow. Conditions may require a much lower speed.

Which use of ordinary music headphones is prohibited for a driver of a private car?
Correct answer: Covering both ears
Ordinary music headphones must not cover or occupy both ears. The law has separate exceptions for certain hearing-protection and assistive devices.

You become sleepy during a long drive. What is the safest response?
Correct answer: Stop in a safe place and rest
Stop somewhere safe, such as a designated rest area. A short nap can help temporarily; adequate sleep is essential.

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.

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.

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.

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.

A bicycle is ahead on a narrow road and a car is approaching opposite you. There is not room to pass safely between them. What should you do?
Correct answer: Slow behind the bicycle, let the car pass, then pass when safe
Slowing separates the encounters. After the oncoming car passes, reassess the road and leave safe bicycle clearance; its departure does not automatically make passing safe.

Unless another limit is posted, what maximum applies to a two-lane undivided California highway?
Correct answer: 55 mph
The usual two-lane undivided highway maximum is lower than the usual freeway maximum. Conditions may require less.

How can traveling substantially faster or slower than the flow of traffic affect safety?
Correct answer: It can increase the chance of a collision
DMV lists speed differences among common collision factors. Still obey speed limits and slow down whenever conditions require.

You are preparing to slow for a driveway turn. Which check helps you avoid being surprised by following traffic?
Correct answer: Check your mirrors while continuing to watch the road ahead
Know where following traffic is before reducing speed. Do not trade away your forward view.

Another car merges into your following gap. How should you rebuild space?
Correct answer: Ease off the accelerator and allow the gap to grow
A gradual speed adjustment creates reaction space without escalating the situation.

An unlit road limits how far ahead you can see. What should guide your speed?
Correct answer: Be able to stop within the distance your headlights illuminate
Your visible path must be long enough for you to recognize a hazard and stop.

You have remained beside another car, just behind its driver, for several minutes. What is safer?
Correct answer: Adjust your position safely to avoid lingering in its blind spot
Avoid prolonged side-by-side driving and keep room to maneuver.

You are late and consider following very closely to pressure the driver ahead to speed up. What should you do instead?
Correct answer: Keep a safe gap and avoid trying to intimidate the other driver
Pressure tactics create conflict and leave less room to respond. Being late does not justify aggressive driving.

The posted maximum is 65 mph, but rain and traffic make that speed unsafe. What does the sign mean for your speed?
Correct answer: 65 mph is a ceiling, and you must choose a lower safe speed for the conditions
A maximum limit is not a required target. Conditions can require a slower speed even when the posted limit has not changed.

Darkness makes it harder to judge hazards ahead. Besides reducing speed, how should you adjust the gap behind another car?
Correct answer: Allow a greater following distance than in good daylight conditions
Extra space provides more time to respond when visibility is reduced. This is general safe-driving guidance, not a separate fixed California nighttime-distance law.
