7.3 Emergencies, Vehicle Breakdowns & Collisions

Emergencies, Vehicle Breakdowns & Collisions

Vehicle mechanical failures, skids, and roadside emergencies occur with little warning. Drivers who understand correct defensive procedures can handle critical equipment malfunctions calmly, prevent minor mishaps from turning into fatal crashes, and comply fully with North Carolina post-collision laws.

Vehicle Mechanical Emergencies & Corrective Actions

When mechanical failure occurs while driving at highway speeds, executing the correct sequence of actions within seconds is vital.

1. Tire Blowout or Sudden Flat Tire

A tire blowout is a sudden loss of tire air pressure, accompanied by a loud pop or thumping sound and a heavy pull toward the side of the blown tire.

• Do NOT slam on the brakes: Sudden braking when a tire blows causes the vehicle to pull violently toward the flat tire, often causing a rollover crash.
• Grip the steering wheel firmly with both hands at the 9 and 3 o'clock positions to maintain straight directional control.
• Ease off the gas pedal smoothly: Allow the vehicle to slow down gradually under its own momentum.
• Steer straight along your lane until speed drops below 30 mph, then activate your turn signal and pull safely onto the right shoulder of the road.

Tire Blowout Response Sequence:
[1. Grip Wheel Firmly] --> [2. Ease Off Accelerator] --> [3. Steer Straight] --> [4. Signal & Pull to Shoulder when Slow]
CRITICAL: Do NOT Slam on Brakes!

2. Total Brake Failure

If pressing the brake pedal results in no stopping resistance or pedal travel to the floorboard:

1. Pump the brake pedal rapidly: Pumping the pedal several times may build up sufficient residual hydraulic pressure to slow the vehicle.
2. Shift to a lower transmission gear: Shifting into lower gears utilizes engine compression braking to reduce speed.
3. Gradually apply the emergency/parking brake: Pull the parking brake lever or press the parking brake pedal gradually while holding down the lever release button. This allows you to modulate rear wheel braking without locking the rear tires into a skid.
4. Search for an escape path: Look for uphill road inclines, open fields, or runaway truck ramps to bring the vehicle to a stop.

3. Sticking Gas Pedal (Accelerator Malfunction)

If your gas pedal sticks or the throttle linkage freezes while driving:

1. Shift the transmission directly into NEUTRAL (N): Shifting to neutral immediately cuts engine power from reaching the drive wheels, even if the engine revs at high RPM.
2. Apply firm, steady pressure to the brake pedal.
3. Signal and steer safely to the shoulder of the road.
4. Turn off the ignition ONLY after coming to a complete stop.

Critical Warning: Never turn the ignition key to the "LOCK" position while the vehicle is moving. Turning the key to LOCK engages the steering wheel lock, disabling steering control entirely and causing a catastrophic crash.

4. Off-Road Recovery (Wheels Dropping Off Pavement)

If your right tires drop off the edge of the paved road onto a low shoulder or dirt strip, panicking and yanking the wheel left causes the vehicle to shoot across the centerline into oncoming traffic.

1. Do NOT jerk the steering wheel back onto the road immediately.
2. Ease off the accelerator pedal and hold the wheel straight along the shoulder.
3. Brake gently if necessary to bring speed down under 25 mph.
4. Check for oncoming and trailing traffic, activate your left signal, and turn the steering wheel approximately one-quarter turn to the left to climb smoothly back onto the paved highway.

Skids & Skid Control Dynamics

A skid occurs when vehicle tires lose rolling friction and traction on the road surface. Skids are caused by driver error: braking too hard, steering too sharply, or accelerating too fast on slippery surfaces.

Correcting a Rear-Wheel Skid (Oversteer)

In a rear-wheel skid, the rear of the vehicle slides out to the left or right (fishtailing). To regain control:

1. Steer IN THE DIRECTION OF THE SKID: Turn your steering wheel in the exact direction that the rear of the vehicle is sliding (or the direction you want the front of the car to go). For example, if the rear of your car slides to the right, steer to the right. If it slides to the left, steer to the left.
2. Do NOT touch the brake pedal or gas pedal: Pressing the brake locks the wheels further, while pressing the gas breaks remaining tire grip.
3. Prepare for a counter-skid: As the car straightens out, it may whip back in the opposite direction. Be ready to steer smoothly back in the opposite direction to prevent a secondary skid.

Rear-Wheel Skid Correction:
Rear Slides RIGHT -------> Turn Steering Wheel RIGHT
Rear Slides LEFT  <------- Turn Steering Wheel LEFT
Foot Control: OFF Brake & OFF Accelerator!

Collision Duties & Reporting Laws in North Carolina

Traffic accidents must be handled strictly according to North Carolina legal requirements.

Immediate Duties at an Accident Scene

If you are involved in a traffic collision, you MUST:

1. Stop immediately at or as close to the crash scene as possible without blocking traffic unnecessarily.
2. Render reasonable assistance to any injured persons (call 911 immediately; do not move an injured person unless there is immediate danger of fire or explosion).
3. Protect the scene: Turn on hazard warning lights and set up warning flares or triangles if available.

Required Information Exchange

All drivers involved in a collision must exchange the following information:

• Driver's full name and home address
• Driver license number and state of issuance
• Vehicle registration number and license plate number
• Motor vehicle liability insurance company name and policy number

Mandatory Crash Reporting Threshold in NC

Under North Carolina law, a driver involved in a collision MUST immediately notify the nearest law enforcement agency (State Highway Patrol, local municipal police, or county sheriff) if the crash results in:

• Personal Injury to any person,
• Death of any person, OR
• Total Property Damage of $1,000 or more.

Failing to stop at the scene of a crash (Hit and Run) involving injury or death is a severe felony offense under North Carolina law, carrying mandatory driver license revocation and prison sentences.
