California Driver Safety and Road Rules

Seat Belt Requirements and Safety Mechanics

• Legal Mandates and Penalties

  • Drivers and all passengers are required to wear seat belts.

  • A citation may be issued for failure to wear a seat belt.

  • Drivers can be cited if any passenger under the age of $16$ is not wearing a seat belt.

• Survival and Vehicle Dynamics

  • Using both the lap belt and shoulder harness significantly increases the probability of survival in most collision types.

  • During a collision, the vehicle stops abruptly; however, occupants continue moving at the same speed they were traveling until they strike the dashboard or windshield.

  • In side-impact collisions, the force can push occupants back and forth across the seat. Seat and shoulder belts maintain the occupant's position, assisting in vehicle control and minimizing serious injuries.

• Impact Mechanics (Driver's Side Collision)

  • Upon being struck on the driver's side, the occupant is first thrown against the driver's side door.

  • The occupant then "rebounds" and is thrown toward the passenger side door.

• Proper Seat Belt Adjustment

  • Shoulder Harness: Wear the harness across the shoulder and chest with little to no slack. It must never be worn under the arm or behind the back.

  • Lap Belt: Adjust the belt so it is snug and lies low across the hips. Improper placement can lead to the occupant sliding out of the belt during a crash.

  • Pregnancy Guidelines: Wear the lap belt as low as possible, positioned under the abdomen. The shoulder strap should be placed between the breasts and to the side of the abdominal bulge.

Child Restraint Systems and Age/Height Requirements

• General Rule

  • Children must be secured using a federally-approved child passenger restraint system or safety belt based on age and height.

• Specific Criteria

  • Under $2$ Years Old, Under $40$ Pounds, and Under $3$ Feet $4$ Inches Tall: Must be secured in a rear-facing child passenger restraint system.

    • Front Seat Prohibition: A child in a rear-facing restraint system is prohibited from riding in the front seat if the vehicle is equipped with an airbag.

  • Under $8$ Years Old or Less Than $4$ Feet $9$ Inches Tall: Must be secured in a child passenger restraint system in a rear seat.

  • Exceptions for Front Seat Placement (Under $8$ Years Old): Children may ride in the front seat in a federally-approved restraint system if:

    • There is no rear seat.

    • The rear seats are side-facing jump seats.

    • The rear seats are rear-facing seats.

    • The restraint system cannot be installed properly in the rear seat.

    • All rear seats are occupied by children aged $7$ years or younger.

    • Medical reasons dictate the child must ride in the front seat.

  • Age $8$ or Older, or at Least $4$ Feet $9$ Inches Tall: May use a properly secured safety belt meeting federal standards.

• Maintenance and Verification

  • Local law enforcement or fire departments offer installation checks for restraint systems.

  • Restraint systems must be updated for size as the child grows.

Air Bag Safety and Vehicle Occupancy Laws

• Air Bag Positioning

  • Occupants should maintain a distance of at least $10$ inches from the air bag cover.

  • Measured from the center of the steering wheel to the breastbone.

  • Passengers should also maintain a $10$-inch distance from the passenger-side air bag.

  • If a driver cannot safely sit $10$ inches away while maintaining vehicle control, they should contact a dealer or manufacturer for advice on moving back.

  • Children seated adjacent to side air bags are at risk of serious or fatal injury.

• Unattended Children and Pets

  • It is illegal to leave a child aged $6$ years or younger unattended in a vehicle.

  • Exception: A child may be left if supervised by a person at least $12$ years old.

  • Leaving children or animals in a hot vehicle is both dangerous and illegal. Internal temperatures rise rapidly in the sun, even with windows cracked, potentially causing dehydration, heat stroke, and death.

Speed Management and the Basic Speed Law

• California Basic Speed Law

  • Drivers may never drive faster than is safe for the current road conditions, regardless of the posted speed limit.

• Factors Determining Safe Speed

  • Number and speed of other vehicles on the road.

  • Road surface conditions (smooth, rough, gravel, wet, dry, wide, or narrow).

  • Presence of bicyclists or pedestrians.

  • Weather conditions (rain, fog, snow, wind, or dust).

  • Traffic congestion; drivers should avoid weaving in and out of freeway lanes to reduce congestion.

• Maximum Speed Limits

  • Ideal maximum for most highways: $65\,mph$.

  • Two-lane undivided highways: $55\,mph$.

  • Vehicles towing trailers: $55\,mph$.

Handling Hazards and Driving Emergencies

• Choosing Between Multiple Hazards

  • If dangers exist on both sides (e.g., parked cars on the right and oncoming traffic on the left), provide more space to the greater danger.

  • If facing an oncoming vehicle and a bicyclist, handle one at a time: slow down, let the vehicle pass, then move left to allow at least $3$ feet of space to pass the bicyclist.

• Tire Blowouts (NHTSA Recommendations)

  • Do not panic, brake suddenly, or abruptly release the accelerator.

  • Hold the steering wheel with both hands.

  • Maintain speed if safe and possible, then gradually release the accelerator.

  • Correct steering to stabilize; look and steer in the desired direction of travel.

  • Once stable, slow down and pull off the road safely.

• Driving Off the Pavement

  • Grip the steering wheel firmly.

  • Remove foot from the accelerator and brake gently.

  • Check traffic behind and carefully steer back onto the pavement without using excessive force.

• Extreme Temperature Conditions

  • Extreme Heat: Monitor the temperature gauge, avoid high speeds for long periods, and turn off the air conditioner.

  • Extreme Cold: Monitor the temperature gauge (check antifreeze levels) and use the defroster or slightly open windows to prevent fogging.

Disabled Vehicles and Roadside Assistance

• Protocol for Freeway Breakdowns

  1. Pull over safely to the right shoulder.

  2. Exit the vehicle from the right side, away from traffic.

  3. Dial $511$ or use a call box for help.

  4. Return to the vehicle from the right side and wait inside with the seat belt fastened.

  5. Use emergency flashers at your discretion for visibility.

  • Only stay outside the vehicle if there is a guardrail or a safe area away from freeway lanes.

• California Highway Patrol (CHP) Freeway Service Patrol (FSP)

  • FSP provides free roadside services during commute times in specific areas.

  • FSP services include: Jump-starting batteries, refilling radiators, taping hoses, changing flat tires, providing one gallon of gas, and reporting collisions to CHP.

  • If the vehicle cannot start, FSP will tow it free of charge to a CHP-approved location (not to private residences or repair shops).

  • FSP does not tow motorcycles or assist in collisions unless directed by CHP.

• Vehicles on Railroad Tracks

  • Train Approaching/Lights Flashing: Immediately exit and run diagonally away from the tracks in the direction the train is coming from. Call $911$.

  • No Train Visible: Exit the vehicle. Call the number on the railroad crossing post or metal control box and provide the crossing number, then call $911$.

Distracted Driving and Modern Technology

• Sources of Distraction

  • Using phones/navigation, interacting with children/pets, adjusting music, and personal grooming (makeup/shaving).

• Cell Phone Laws

  • Driving while using a handheld cell phone is illegal.

  • Adult Drivers: Use hands-free mode only when necessary. Pull off the road to make calls and do not read or send texts/emails while driving.

  • Mounting Rules: Phones must be mounted on the windshield, dashboard, or console without blocking the view. Only single-swipe or touch features are permitted.

  • Minors: Illegal to use any electronic wireless device for calls or texts. Exception: Emergency assistance calls.

• Advanced Technology

  • Drivers must be aware of Self-driving vehicles and Advanced Driver Assistance Systems (ADAS), as they may react differently than human drivers.

Carbon Monoxide Awareness

• Risk Factors

  • Gas-powered vehicles produce carbon monoxide, an odorless, deadly gas. Never start a vehicle in a closed garage.

• Symptoms of Poisoning

  • Tiredness and yawning.

  • Dizziness and nausea.

  • Headache and ringing in the ears.

  • If symptoms occur, the vehicle's exhaust system must be inspected immediately.
