In good conditions, you reach a roadside post one second after the car ahead. What does the guide's three-second rule tell you?
Correct answer: Drop back to increase the following interval.
Count from when the car ahead passes a fixed object until you pass it. Less than three seconds indicates too little space under this basic guide rule.

Rain reduces traction and visibility. What should happen to your following space?
Correct answer: Increase it beyond the normal dry-road interval.
Poor conditions increase the time and distance needed to respond. Leave more room and reduce speed rather than treating a dry-road interval as sufficient.

Brakes are only one part of stopping. What else must your stopping space allow for?
Correct answer: The distance traveled while recognizing and reacting to the hazard.
The vehicle keeps moving before the brakes take effect. Perception and reaction distances are added to braking distance.

Heavy rain makes the posted maximum speed unsafe. What should you do?
Correct answer: Reduce speed to one appropriate for the conditions.
A posted maximum assumes favorable conditions. Louisiana's general speed rule also requires a reasonable speed for the road, traffic, light and weather.

After passing a truck, why should you avoid cutting closely in front of it?
Correct answer: The truck needs that space to stop safely.
Large trucks generally require more stopping room. Taking away their space cushion can create a rear-end collision if you then slow or stop.

You cannot see the truck driver's face in the truck's side mirror. What is the safest assumption?
Correct answer: The driver may not be able to see your car.
Avoid lingering in a truck's blind areas. Increase separation or complete a safe, legal pass so that the driver can better locate you.

A large truck is turning at the intersection ahead. What should you provide?
Correct answer: Extra room rather than squeezing into its turning space.
A truck needs more space to maneuver, and its blind spots change throughout the turn. Stay clear of the path swept by the vehicle.

A motorcycle is riding near one side of its lane. May your car use the rest of that same lane to pass it?
Correct answer: No; give the motorcycle the full lane.
Motorcyclists may need to change lane position to avoid hazards. Pass as you would another vehicle instead of squeezing alongside in the same lane.

A motorcycle approaching your driveway has a turn signal flashing. Is that alone enough to enter its path?
Correct answer: No; wait until the rider's movement clearly shows the turn.
A motorcycle's signal may not cancel automatically. Do not assume the rider will turn until the maneuver is clear.

What following interval does the guide recommend as a minimum when driving behind a motorcycle?
Correct answer: At least four seconds.
The guide recommends at least four seconds behind a motorcycle. Wet roads and other hazards call for additional room.

Why should you be especially cautious when rain first begins after a dry period?
Correct answer: Water mixes with oil and grease, making the pavement slippery.
Early rain can loosen accumulated oil and grease before they wash away. Reduce speed and leave extra following space.

Your tires begin riding on water and traction falls away. What is the appropriate initial response?
Correct answer: Ease off the gas and steer gently.
Hydroplaning separates the tires from the pavement. Smoothly easing speed helps them regain contact; harsh control inputs can worsen the loss of control.

Which combination helps reduce hydroplaning risk?
Correct answer: Lower speed, adequate tire tread and recommended tire pressure.
Tread channels water away, proper inflation supports tire contact, and lower speed reduces the chance of riding up on the water layer.

Water covers the road ahead, and you cannot judge the pavement beneath it. What should you do?
Correct answer: Turn around safely and find another route.
Floodwater can conceal a washed-out roadway or dangerous current. Apparent shallowness is not reliable evidence that the road can be crossed.

At night, an oncoming vehicle is 400 feet away. Which beam should you use?
Correct answer: Low beam.
The guide requires lower beams when approaching within 500 feet of another vehicle. Do not dazzle an approaching driver.

You are following another vehicle at night from 150 feet away. Which headlights are appropriate?
Correct answer: Low beams rather than high beams.
Lower beams are required when following within 200 feet. High beams can glare into the leading driver's mirrors.

Rain makes windshield wipers necessary during daylight. What lighting should you use in Louisiana?
Correct answer: Low-beam headlights.
The guide requires low-beam headlights when windshield wipers are needed. Headlights also help other drivers see your car in the rain.

Your stopping distance would carry you beyond the road you can see in your headlights. What adjustment is needed?
Correct answer: Slow down so you can stop within the visible distance.
At night, your visible stopping space is limited. Choose a speed that leaves enough room to recognize a hazard, react and stop.

Traffic is backed up beyond a railroad crossing and there is not enough space for your whole car on the far side. What should you do?
Correct answer: Wait before the tracks until you can clear them completely.
Never enter a crossing unless the whole vehicle can clear it. A green roadway signal or moving queue does not guarantee safe storage beyond the tracks.

Steam rises from under the hood and you stop safely. What should you do about the radiator cap?
Correct answer: Keep it closed and wait for the engine to cool.
The guide says to stop, shut off the engine and wait for cooling. Opening a hot pressurized radiator can cause serious injury.
