A tire suddenly blows out while you are driving. Which response best follows NHTSA's control-first guidance?
Correct answer: Hold the wheel, ease off the accelerator gradually and slow under control.
Keep both hands on the wheel and stabilize the vehicle. Avoid abrupt braking or suddenly releasing the accelerator. Once the vehicle is controlled, continue slowing and leave the road when safe; there is no universal speed at which this becomes safe.

The number on your tire's sidewall is higher than the cold inflation pressure shown on the vehicle's door placard. Which value should guide normal inflation?
Correct answer: The vehicle manufacturer's recommended cold pressure.
Use the vehicle placard or owner's manual, not the maximum number on the tire. The vehicle maker's recommendation accounts for the vehicle; front and rear recommendations may differ.

For an accurate routine cold-tire pressure check, how long does NHTSA say the vehicle should have been parked without being driven?
Correct answer: At least three hours.
NHTSA defines cold tires for this check as tires not driven on for at least three hours. Measure with a gauge and compare with the vehicle's recommended cold pressure, including the spare as applicable.

Your tire-pressure warning light is off, and the tires look inflated. Does that remove the need for routine pressure checks?
Correct answer: No; use a gauge for regular monthly checks.
TPMS warns when a tire is significantly underinflated; it does not replace maintenance. Tires can be underinflated without looking flat, so NHTSA recommends monthly gauge checks.

A tire's tread has worn down until it is level with the built-in treadwear bars. What should you do?
Correct answer: Replace the tire rather than continue using its worn tread.
The raised wear indicators show that the usable tread has worn down. NHTSA says tires are unsafe and should be replaced at 2/32 inch of tread; extra air cannot replace missing tread.

A full-size spare has deep tread because it has sat unused for years. What is the safer conclusion about its condition?
Correct answer: It may have aged; check its age and condition before relying on it.
Rubber and other tire components change with age even when a tire is seldom used. Inspect the spare and follow the tire and vehicle makers' guidance; deep tread alone does not establish that it is safe.

Your car has functioning antilock brakes, and you must brake hard on a slick road. How should you operate the brake pedal?
Correct answer: Apply firm, continuous pressure while steering as needed.
ABS manages wheel lockup while braking. NHTSA advises firm, continuous pedal pressure with ABS, rather than pumping it. Learn your vehicle's system; ABS does not make a slick surface safe at any speed.

You are installing replacement floor mats before a wet-weather trip. What matters most for pedal safety?
Correct answer: Use the correct fit and secure the mats as the manufacturer directs.
An improperly fitted mat can interfere with the accelerator or brake. Use mats sized for the vehicle and its retention clips according to the manufacturer's installation instructions.

Your vehicle catches fire and you have stopped safely and switched off the engine. What is the next priority?
Correct answer: Evacuate, stay at least 100 feet from the car and away from traffic, and call 911.
USFA directs occupants to leave, stay at least 100 feet from the burning vehicle and well away from traffic, and call 911. Do not return to the vehicle or attempt to fight the fire yourself.

After safely leaving a vehicle with a suspected fire under its hood, should you lift the hood to inspect it?
Correct answer: No; leave it closed and stay away while help is called.
USFA warns against opening the hood or trunk when fire is suspected inside because opening it may intensify the fire. Stay away and let emergency responders deal with it.

You are safely stopped in a snowstorm and plan to use the engine intermittently for warmth. What must you check to reduce carbon-monoxide risk?
Correct answer: That snow is not blocking the exhaust pipe.
NHTSA says to keep the exhaust clear and run the engine only sporadically, long enough for warmth. Avoid long periods of running with windows closed or in an enclosed space; a blocked exhaust can create a deadly hazard.

After overnight ice and snow, you have cleared a small viewing hole in the windshield. What should you do before starting your trip?
Correct answer: Clear the hood, windows and roof of ice and snow.
The Louisiana guide calls for clearing ice and snow from the hood, windows and roof before driving. A small windshield opening does not provide the visibility needed to check traffic around the vehicle.

Your right wheels roll onto a firm, clear shoulder beside the pavement. What is the safer immediate response?
Correct answer: Keep control, slow gradually and check traffic before returning safely.
Do not snap the vehicle back onto the pavement. The guide warns that an abrupt return can send it into opposing traffic. Reduce speed and choose a safe reentry; a drop-off requires additional care.

In a car without ABS, the rear starts sliding to the right on a slippery road. Which response matches the guide's skid-recovery advice?
Correct answer: Ease off the accelerator and steer smoothly right without oversteering.
For this rear-end skid, steer in the direction the rear is sliding so the front follows the intended path. Avoid braking in the specified non-ABS case, avoid excessive steering and straighten the wheels as control returns.

You must drive in fog, but switching to high beams makes the view look whiter and harder to see through. Which lighting choice is appropriate?
Correct answer: Use low-beam headlights and reduce speed for visibility.
The National Weather Service recommends low beams in fog. High beams create reflected glare and can make the road harder to see. Leave ample space and drive slowly enough for the limited view.

The pavement beside you looks clear on a freezing morning. Why should an approaching bridge or shaded section still concern you?
Correct answer: It can freeze first and remain icy longer than nearby roadway.
Bridges, overpasses and shaded areas can become icy before other road surfaces and remain frozen longer. Do not use a clear-looking approach as proof of safe traction on the structure.

A curve ahead is covered by wet fallen leaves. How should you treat that patch?
Correct answer: As a potentially slippery surface, with a lower approach speed.
The guide warns that wet leaves can create slippery conditions. Reduce speed before reaching the patch and avoid abrupt control changes rather than assuming the leaf cover provides traction.

Your car stalls on a railroad crossing and will not move. You cannot see or hear a train. What should you do first?
Correct answer: Get everyone out immediately and well away from the car and tracks.
NHTSA says to evacuate immediately even when no train is visible. Move away from both the tracks and the vehicle to avoid a train or debris; do not wait inside to see whether one arrives.

Everyone is safely away from a car stalled on the tracks. A blue emergency notification sign is visible at the crossing. Which number should you call?
Correct answer: The emergency number shown on the blue sign.
Call the emergency notification number on the blue sign to report the blocked crossing. NHTSA says to call 911 if the sign is not visible. Make the call from a safe place away from the tracks and car.

A child's thick winter coat prevents the car-seat harness from fitting snugly. What should you do?
Correct answer: Use thin warm layers, secure the harness, then add a blanket over it.
Bulky coats can interfere with harness fit. NHTSA recommends thin warm layers, with a blanket or coat placed around the child after the harness is properly snug and secured.
