Parking lot safety

Parking lot incidents cluster in the drive aisles, not the stalls: backing collisions, pedestrians crossing between parked cars, and drivers cutting through at 20–25 mph. The cheapest control is physical speed reduction — a bolt-down rubber speed bump forces 5–10 mph at the points where aisles, entrances and walkways meet, for $260–$520 in materials per 12 ft lane plus freight. Signage and striping support it, but only a physical device changes driver behavior.

2.4-inch heavy-duty rubber speed bump with black and yellow segments, white directional arrows and bolt holes

Recommended model

3-Inch Modular Rubber Speed Bump

Cars and light trucks dominate most lots, so the 3 in modular profile gives the biggest speed reduction per dollar and can be re-configured if you restripe the lot.

Height: 3 in
Center module: 39 in and 20 in
End caps: 10 in each
Width (travel length): 15 in
Target speed: ≤ 10 mph
Material: Recycled rubber, UV stable

Fix the aisle before the sign

A 10 MPH sign is advisory on private property. A 3 in bump is physical: the driver slows whether or not they read anything.

Protect the pedestrian path

Place a bump ahead of the crossing, not on it — never across a marked accessible route — so drivers are already at walking-speed when they reach it.

Document the effort

Reflective bands, MUTCD W17-1 signage at the entrance and a dated install record are what a carrier looks for after a lot incident.

Frequently asked

What is the most common parking lot accident?

Low-speed collisions in the drive aisle: a vehicle backing out of a stall struck by a car moving through the aisle, and pedestrians stepping out between parked vehicles. Both get far less severe when aisle speed is physically held near 5–10 mph.

What speed limit should a parking lot have?

5–10 mph is the normal posted figure for commercial lots. On private property the posted number is advisory, so pair it with a physical device if you need drivers to actually comply.

Are speed bumps required in a parking lot?

They are not federally required. They are a voluntary risk control most property owners add after complaints or an incident, and they document a good-faith effort for insurance purposes.

How many speed bumps does a lot need?

Count the drive aisles, place one every 150–250 ft along each, add one inside the entrance, and keep every unit at least 25 ft from stop bars, turns and crossings. Most lots need a handful of lanes, not dozens.

How long does installation take?

Bolt-down install takes two people about 30 minutes per 12 ft lane: position the modules, mark the bolt holes, hammer-drill the asphalt or concrete, and torque the anchors flush. No paving contractor and no cure time.

Do you ship nationwide?

Yes. Every kit is in stock in the USA and ships by LTL freight to all 48 contiguous states. Pallet and container pricing is available for volume orders, and freight is quoted to your ZIP code.
