Parking Speed Bumps: A Key to Safer Parking Lots

What Are Parking Speed Bumps?

Parking speed bumps—also known as speed humps or traffic calming devices—are raised sections of pavement designed to slow down vehicles in parking areas. Typically made from asphalt, rubber, or recycled plastic, these structures force drivers to reduce their speed, improving safety for both pedestrians and vehicles.

Why Parking Lot Safety Matters

Parking lots can be surprisingly dangerous. With limited visibility, unpredictable pedestrians, and vehicles reversing, the risk of accidents is high. Speed bumps help reduce these risks by controlling vehicle speed, promoting cautious driving, and preventing reckless behavior.

Key Benefits of Speed Bumps in Parking Lots

1. Slows Down Traffic

Speed bumps physically force drivers to reduce speed, especially in high-risk areas like entrances, exits, and pedestrian crossings.

2. Prevents Accidents

By controlling speed, speed bumps reduce the likelihood of collisions between vehicles and pedestrians or other cars.

3. Enhances Pedestrian Safety

They make crossing parking lots safer for pedestrians, especially in busy retail areas, schools, and office complexes.

4. Discourages Reckless Driving

Drivers tend to be more alert and responsible in areas with visible speed control devices.

Types of Parking Speed Bumps

Traditional Speed Bumps

Short, aggressive bumps designed for maximum speed reduction. Ideal for small lots and private properties.

Speed Humps

Wider and more gradual than speed bumps, speed humps offer smoother transitions, suitable for areas with moderate traffic.

Speed Cushions

Segmented humps that allow wider vehicles like emergency trucks to pass with less disruption while still slowing regular cars.

Design & Placement Considerations

• Height & Width: Typically 3–6 inches high and 12–14 feet wide to balance safety and drivability.

• Placement: Ideal near crosswalks, entrances, and blind spots.

• Spacing: Proper intervals prevent drivers from accelerating between bumps.

• Visibility: Reflective paint and signage are crucial for nighttime visibility and compliance.

Installation and Maintenance

Preparing the Surface

Assess surface conditions and traffic flow before installation. A clean, level surface ensures durability and performance.

Installing the Bumps

Depending on the material, speed bumps can be bolted down or permanently installed using adhesives or anchors.

Ongoing Maintenance

Inspect regularly for wear and damage. Replace worn-out markings and secure loose fixtures to maintain effectiveness.

Common Criticisms & Alternatives

Vehicle Wear and Tear

Excessive or poorly designed bumps can damage suspensions and tires. Proper sizing helps minimize this risk.

Noise and Vibrations

While they reduce speeding, bumps can cause noise—especially in residential areas. Rubber models offer quieter alternatives.

Other Traffic Calming Options

If speed bumps aren’t ideal, consider:

• Raised crosswalks

• Chicanes

• Radar speed signs

• Strategic landscaping or bollards

Final Thoughts

Installing parking speed bumps is a cost-effective way to enhance safety, reduce accidents, and promote responsible driving behavior. Whether you’re managing a retail parking lot, a residential complex, or a school zone, speed bumps are a proven solution for improving pedestrian safety and controlling traffic flow.
