What is the recommended following distance between your vehicle and the one ahead in good weather conditions?
Four seconds
Two seconds
One second
Three seconds
Maintaining a three-second following distance gives sufficient time to react if the vehicle ahead stops suddenly. This rule accounts for average driver reaction time and braking distance under normal conditions. It is widely recommended by driving safety experts as a baseline. .
Before changing lanes, which action is essential to ensure it's safe?
Speed up significantly
Sound your horn
Apply your brakes suddenly
Check your blind spots
Checking blind spots ensures there are no vehicles in areas not covered by mirrors. Relying solely on mirrors can leave you unaware of motorcycles or smaller vehicles. A quick head turn helps prevent collisions. .
When approaching a school zone with flashing lights, what should you do?
Reduce your speed and be prepared to stop
Honk your horn to alert children
Speed up to clear the zone quickly
Maintain your current speed
Flashing lights in a school zone indicate children may be present and require reduced speeds. Slowing down increases your reaction time if a child steps into the roadway. Always observe posted speed limits in these areas. .
What does a steady yellow traffic light indicate?
Stop immediately, even if in the intersection
Caution: the light will turn red soon
Speed up to beat the red light
Proceed through without caution
A steady yellow light warns drivers that the signal is about to turn red. It is not an order to stop immediately if you are already in the intersection. The proper approach is to slow and prepare to stop safely. .
In rainy conditions, which headlights should you use?
Parking lights only
High beams
Low beam headlights
Hazard lights
Low beam headlights improve visibility without causing excessive glare in wet conditions. High beams can reflect off the rain and impair your vision. Using low beams helps other drivers see you. .
If you start to feel drowsy while driving, what should you do?
Open a window and turn up the music
Drink a caffeinated beverage and continue
Increase your speed
Pull over and rest
Drowsiness impairs reaction times and decision-making. Short-term fixes like music or caffeine are unreliable at preventing microsleeps. The safest option is to stop and rest until you're alert. .
What is the best way to handle being tailgated?
Speed up to put distance between you
Gesturing angrily to the driver behind
Maintain speed and increase your following distance
Brake-check to scare them off
By increasing your own following distance, you give yourself more time to react if traffic slows. Sudden braking can provoke a collision from the tailgater. Maintaining a consistent speed also reduces risk. .
Which gear should you use when descending a steep hill?
High gear
Neutral
Low gear
Park
Low gear uses engine braking to help control your speed without overusing the brakes. Relying solely on brakes can cause overheating and fade. Leaving the transmission in drive or neutral removes engine braking benefits. .
How should you apply brakes in a vehicle equipped with ABS (anti-lock braking system) during an emergency stop?
Tap the brakes lightly and release
Press and hold the brake pedal firmly
Pump the brakes rapidly
Shift into neutral and brake
ABS is designed to prevent wheel lockup by modulating brake pressure automatically. Pressing and holding the pedal allows the system to operate correctly. Pumping brakes in an ABS vehicle defeats its purpose. .
At approximately what speed does hydroplaning become a significant risk on a wet road?
15 mph
75 mph
55 mph
35 mph
Hydroplaning can begin around 35 mph when water prevents tire contact with the road surface. Reduced traction makes steering and braking ineffective. Slowing down in heavy rain significantly lowers the risk. .
How many seconds ahead should you scan the road in normal driving conditions?
12 seconds
20 seconds
5 seconds
8 seconds
Scanning 12 seconds ahead gives drivers time to detect hazards and plan responses. This forward-looking habit is recommended by defensive driving courses. It allows for smoother braking and lane changes. .
After passing a large truck, why should you avoid lingering beside it?
It improves your fuel efficiency
It is illegal to pass a truck
Trucks have large blind spots
The truck may pull over suddenly
Large trucks have significant blind spots on both sides which can hide your vehicle. Crossing quickly reduces the chance the truck driver won't see you. Always move ahead far enough before merging back. .
If your vehicle begins to skid, what is the correct steering response?
Steer opposite to the skid
Turn off the ignition
Brake hard and hold
Steer into the skid
Steering into the skid helps realign the tires with the direction of travel and regain traction. Over-correcting by steering the other way can worsen the skid. Gentle inputs are best until control is restored. .
When merging onto a highway, you should:
Stop at the end of the on-ramp
Match the speed of traffic before merging
Honk to warn other drivers
Merge as early as possible
Accelerating on the ramp to match highway speeds allows you to merge smoothly without disrupting traffic flow. Stopping on a ramp is dangerous and illegal. Always use mirrors and signal before merging. .
What is the primary purpose of rumble strips along the edge of the roadway?
Improve drainage
Warn inattentive drivers of lane departure
Mark pedestrian crossings
Reduce tire wear
Rumble strips provide an audible and vibrating alert when drivers drift out of their lane. This warning helps prevent run-off-road crashes due to inattention or drowsiness. They are especially useful on rural highways. .
When a stopped school bus has its red lights flashing and stop arm extended, drivers approaching from either direction must:
Stop and remain stopped until lights are off
Slow down and pass with caution
Honk to alert children
Turn on hazard lights and proceed
Flashing red lights and the stop arm signal that children are boarding or exiting the bus. Traffic in both directions must stop to ensure child safety. Passing a bus while lights are flashing is illegal in all states. .
What is the legal blood alcohol concentration (BAC) limit for drivers over 21 in most U.S. states?
0.08%
0.10%
0.05%
0.02%
A BAC of 0.08% is the legal limit for drivers 21 and over in most U.S. jurisdictions. At this level, impairment of motor skills and reaction time increases crash risk significantly. Driving at or above this limit can lead to DUI penalties. .
How far in advance should you signal before making a turn in urban areas?
100 feet
200 feet
25 feet
50 feet
Signaling at least 100 feet before a turn in urban areas gives other road users ample warning. This distance is typically marked by pavement markers or signposts. Proper signaling helps prevent rear-end collisions. .
When is it safe to return to your lane after passing another vehicle?
When the passed vehicle slows down
Immediately after signaling
When you see the passed vehicle completely in your rearview mirror
As soon as you finish accelerating
You should only return when you can see the entire front of the passed vehicle in your inside mirror. This confirms you have enough space to merge safely. Premature lane changes can cause collisions. .
If you enter a curve too quickly, what should you do?
Downshift and coast through
Brake hard while turning
Increase speed to stabilize the vehicle
Gradually slow down before the curve
Slowing down before entering a curve helps maintain traction and control. Braking during the turn can cause skids or loss of steering. Proper speed adjustment beforehand is key to safe cornering. .
If your non-ABS brakes lock up, what is the recommended technique to regain braking control?
Turn off the engine
Pump the brake pedal
Shift into neutral
Hold the brake pedal down
Pumping the brakes on a locked-wheel skid restores traction by allowing wheels to rotate momentarily. This technique mimics ABS action in older vehicles. Continuous firm pressure will keep the wheels locked and skid out of control. .
What is the safest response to a tire blowout while driving at highway speed?
Hold the steering wheel firmly and let the vehicle slow down gradually
Immediately shift into neutral
Steer sharply to counteract the pull
Brake hard and steer to the shoulder
Holding the wheel firmly prevents oversteering while the vehicle slows naturally due to drag. Sudden braking or sharp turns can cause loss of control. Once slowed, steer smoothly to the shoulder and stop. .
At an unmarked intersection where no traffic signals or signs are present, which driver has the right-of-way?
The driver on the left
The faster-moving vehicle
The driver on the right
The driver who reaches the intersection first
At unmarked intersections, drivers must yield to vehicles approaching from the right. The first vehicle to reach the intersection has the right-of-way only if no one is on its right. This rule prevents confusion and collisions. .
Which of the following is the correct order of steps in the SIPDE defensive driving process?
Search, Identify, Decide, Predict, Execute
Identify, Search, Predict, Decide, Execute
Search, Predict, Identify, Decide, Execute
Search, Identify, Predict, Decide, Execute
The SIPDE process stands for Search, Identify, Predict, Decide, and Execute. It provides a structured approach to hazard recognition and response. Following these steps in order improves situational awareness and decision-making. .

Cheat Sheet

  1. Maintain a Safe Following Distance -

    Use the 3-second rule to judge the space between you and the vehicle ahead: pick a fixed point, and if you pass it in less than 3 seconds, you're too close. Increasing to 4 - 6 seconds in poor weather or heavy traffic boosts safety margins. This simple guideline appears often in defensive driving quiz questions and answers to test your grasp of accident prevention.

  2. Master the SIPDE Hazard Recognition System -

    SIPDE stands for Scan, Identify, Predict, Decide, and Execute - a five-step process advised by AAA and NHTSA to spot and react to hazards. For example, predict that a pedestrian near the curb might step into the road, then decide and execute a controlled slow-down. This mnemonic trick is a staple in safe driving trivia and defensive driving facts quizzes.

  3. Calculate Total Stopping Distance -

    Total stopping distance combines reaction distance (speed × reaction time) and braking distance (v² ÷ (2μg)), where μ is the friction coefficient and g is gravity. At 60 mph on dry pavement, expect roughly 264 ft total; wet roads can nearly double that distance. Questions on an accident prevention quiz often probe this physics-based formula.

  4. Minimize Distractions Inside the Vehicle -

    The NHTSA reports that texting multiplies crash risk by 23×, so stow your phone and avoid other distractions like adjusting the radio while driving. Remember the ABCD mnemonic - Alcohol, Bio-rhythms (fatigue), Cell phones, Daydreaming - to recall four major distraction types. Driving safety quiz questions and answers frequently focus on your strategies to keep attention on the road.

  5. Adapt to Adverse Conditions -

    Reduce speed by at least one-third in rain, snow, or fog and increase your following distance to 6 seconds or more to compensate for longer stopping distances. Use your headlights in low-visibility conditions to stay visible, as recommended by IIHS studies. This principle is a common topic in safe driving trivia and defensive driving quiz challenges.
