Driving Emergencies and Flash Floods

Key points

1. If brakes fail, pump the pedal, and if that does not work, use the emergency parking brake.

   “Try pumping the brake pedal. If the brakes still do not respond: Use the emergency parking brake.”
   Nevada Driver's Handbook, Handbook p. 58

2. If the gas pedal sticks, shift to neutral, brake and pull off to the right.

   “Shift to neutral. Apply the brakes. Pull off the highway to the right (if possible) and stop.”
   Nevada Driver's Handbook, Handbook p. 58

3. If smoke comes from the hood, slow down, pull off and turn off the ignition immediately.

   “If smoke comes from under the hood, slow down, pull off the road and turn off the ignition immediately.”

4. If a fire gets out of control, move at least 100 feet away.

   “If you have no way to stop the fire or if it gets out of control, move well away (at least 100 feet) from your vehicle.”
   Nevada Driver's Handbook, Handbook p. 58

5. In a blowout, grip the wheel, ease off the gas and do not hit the brakes.

   “Grip the steering wheel firmly. Ease up on the gas pedal to slow down. Do not hit the brakes!”
   Nevada Driver's Handbook, Handbook p. 59

6. If a car comes at you in your lane, slow down, sound your horn, flash your lights and pull right.

   “slow down, sound your horn, flash your headlights and pull as far to the right as you safely can.”

7. Less than 1 inch of water can make you lose control, and most vehicles float in 2 feet or less.

   “Less than 1 inch of water can cause a driver to lose control of his or her car. Most vehicles can float in 2 feet of water or less.”

8. Do not try to drive through a flooded roadway.

Numbers to know

3 questions from the Nevada practice test

1. 1. If your brakes fail and pumping the pedal does not restore braking, what should you try next?

   1. Turn off the ignition and release the steering wheel
   2. Place the vehicle in park immediately while moving downhill
   3. Use the emergency parking brake and shift to a lower gear if possible
   4. Accelerate to reach a repair shop before stopping
   Show answer

   Use the emergency parking brake and shift to a lower gear if possible. When normal braking does not respond, the handbook advises using the emergency parking brake and shifting to a lower gear when possible. Lower gearing can help control speed, especially on a long descent. Selecting park while the vehicle is moving can damage the drivetrain and does not provide a dependable emergency response. Turning off the ignition or accelerating removes control. Keep the vehicle pointed safely, warn others with flashers when possible, and seek a place to stop without creating a secondary collision.

2. 2. If smoke comes from under your hood, what should you do first?

   1. Accelerate until the smoke clears
   2. Pour water over the engine while moving
   3. Slow down, pull off the road, and turn off the ignition
   4. Open the hood immediately beside traffic
   Show answer

   Slow down, pull off the road, and turn off the ignition. Smoke under the hood calls for a controlled move away from traffic and an immediate shutdown of the ignition. Slowing down reduces the chance of losing control, and pulling off the road creates space from moving vehicles. Water can spread burning gasoline, so it is not a safe default. Opening a hot hood without caution can expose you to flames or heat. Once stopped, keep people away from danger and follow the handbook's fire guidance, including moving at least 100 feet away if the fire cannot be controlled.

3. 3. If the accelerator sticks, what should you do after trying to free the pedal?

   1. Shift into park while traveling quickly
   2. Shift to neutral, apply the brakes, and pull off to the right
   3. Pump the accelerator harder until traffic passes
   4. Turn sharply across the centerline
   Show answer

   Shift to neutral, apply the brakes, and pull off to the right. After pressing firmly against a stuck accelerator and releasing it, shift to neutral so engine power no longer drives the wheels. Apply the brakes, move toward the right side when possible, and stop. Selecting park while moving can damage the vehicle or interfere with control, while more accelerator input increases the hazard. Do not make a sudden centerline movement to escape. The practical cue is to separate propulsion from the wheels first, then manage braking and a safe roadside stop.
