7.3 Vehicle Malfunctions, Tire Blowouts, and Crash Protocol

Vehicle Malfunctions, Tire Blowouts, and Crash Protocol

Even well-maintained vehicles can experience sudden mechanical failures while traveling at high speeds on expressways or winding mountain roads. Knowing how to react in the first critical seconds of a mechanical emergency can prevent a catastrophic collision. Furthermore, if a traffic accident occurs, drivers must strictly follow the emergency protocols and statutory duties established under Law 22 (Ley de Vehículos y Tránsito de Puerto Rico).

Handling Vehicle Mechanical Emergencies

1. Tire Blowout (Reventón de Neumático)

A tire blowout is a sudden explosion or sudden loss of air pressure in a tire. A front-tire blowout causes the vehicle to pull violently toward the side of the blown tire; a rear-tire blowout causes the vehicle's tail to fishtail or sway side-to-side.

Blowout Recovery Actions:
[DO NOT BRAKE] -> [GRIP WHEEL FIRMLY] -> [EASE OFF GAS] -> [COAST TO SHOULDER]

• Grip the steering wheel firmly: Use both hands at the 9-and-3 or 8-and-4 positions to maintain directional control against the severe pull.
• Do NOT slam on the brakes: Sudden braking on a blown tire will cause the rim to dig into the asphalt, destabilizing the vehicle and flipping it over.
• Ease off the gas pedal: Allow the vehicle to slow down gradually on its own.
• Signal and pull onto the shoulder: Once the vehicle has slowed below 20 mph, gently steer off the active roadway onto the right shoulder, activate hazard warning lights (luces de emergencia), and set up emergency reflectors or flares.

2. Total Brake Failure (Fallo de Frenos)

If pressing the brake pedal offers no resistance ("pedal goes to the floor"), your hydraulic brake system has failed.

1. Pump the brake pedal rapidly: Pumping may rebuild sufficient hydraulic pressure in a dual-master cylinder system to stop the car.
2. Downshift to a lower gear: Shift the transmission into low gear (L, 2, or manual downshift mode). Engine braking will slow the vehicle down significantly.
3. Apply the emergency / parking brake: Gradually pull the emergency brake lever or push the foot pedal while holding the release button/lever. Do not pull it abruptly, as locking the rear wheels can cause a spinout.
4. Find a safe stopping zone: If open space is available, steer toward an uphill slope, open field, or soft embankment to bring the car to a safe stop.

3. Steering Failure & Accelerator Sticking

• Steering Failure: If steering loses power assist or disconnects, ease off the accelerator, turn on hazard lights, and apply brakes firmly to stop safely on the shoulder.
• Stuck Accelerator: If the gas pedal sticks, shift the transmission immediately into Neutral (N). Apply steady brake pressure, steer safely off the roadway, and turn off the ignition only after stopping. Do not turn the key to the "LOCK" position while moving, as it will lock the steering wheel.

4. Engine Fire

If smoke or flames emerge from under the hood, pull off the road immediately. Turn off the ignition to stop fuel flow. Get all passengers out and move at least 100 feet away. Do not open the hood, as adding oxygen will cause the fire to burst outwards. Call 911 immediately.

Off-Road Pavement Drop-Off Recovery

If your right tires slip off the edge of the paved road onto a low shoulder or dirt surface:

1. Do not jerk the steering wheel back: Trying to steer back onto the asphalt abruptly will cause the tire sidewall to catch the pavement edge, flinging the car across the road into oncoming traffic.
2. Hold the wheel straight and ease off the accelerator.
3. Brake gently until speed is under 25 mph.
4. Check traffic, then turn the steering wheel 1/4 turn to the left to climb back smoothly onto the paved roadway.

Crash Protocols & Legal Obligations Under Law 22

When a traffic crash occurs in Puerto Rico, Law 22 (Artículos 11.01 et seq.) establishes strict legal duties for all involved drivers.

Law 22 Mandatory Accident Protocol:
[STOP IMMEDIATELY] -> [CLEAR TRAVEL LANES (If No Injuries)] -> [RENDER AID] -> [EXCHANGE DATA] -> [REPORT TO POLICE]

1. Mandatory Duty to Stop

Any driver involved in a collision must stop immediately at the scene or as close as possible without obstructing traffic unnecessarily. Leaving the scene of an accident (darse a la fuga / hit-and-run) is a serious crime under Law 22 carrying severe fines, mandatory license revocation, and imprisonment.

2. Moving Vehicles (The "Clear the Travel Lane" Rule)

If an accident involves property damage only (no injuries or deaths) and the vehicles remain operational, Law 22 requires drivers to move the vehicles out of active traffic lanes onto the right shoulder, median, or off-ramp. Leaving driveable vehicles in active lanes creates major traffic jams and causes secondary rear-end collisions.

3. Rendering Aid to Injured Persons

Drivers must render reasonable assistance to anyone injured in the crash. This includes:

• Calling 911 or emergency medical services immediately.
• Keeping injured persons warm and calm.
• Do not move injured persons unless there is an immediate threat of fire, explosion, or submersion.

4. Mandatory Exchange of Information

Drivers involved in a crash must exchange the following identifying information:

• Driver's full legal name and residential address.
• Driver's license number.
• Vehicle registration plate number and vehicle identification number (VIN).
• Auto insurance policy details and provider name.

5. Reporting the Crash to Puerto Rico Police

An official report must be made to the Puerto Rico Police Bureau (Policía de Puerto Rico) whenever a crash results in:

• Any bodily injury or fatality.
• Total or partial disability of any party.
• Property damage exceeding statutory reporting thresholds.

Officers will complete an official police accident report (Informe de Accidente), which is mandatory for insurance claims and legal documentation.
