RUBBER SPEED CUSHIONS

An innovative solution to emergency vehicle concerns on traffic-calmed routes, speed rubber cushions slow cars down without significantly affecting emergency response time. Designed as several small speed rubber humps installed across the width of the road with spaces between them, the speed rubber cushions slow cars down to between 15-20 mph as they ride over them. However, the wider axle of emergency vehicles such as fire trucks and ambulances allows them to straddle the cushions, driving over them without slowing down.

Rubber speed cushions from TS&L are made of interlocking units that snap together on site, typically 3 inches high and 7 feet long, for a speed cushion installation that's quick to complete and easy to reconfigure later. They're a practical fit for any residential street or emergency response route where slowing speeders matters as much as keeping response times fast.

Traffic Calming Design

The sloped profile of the speed cushions forces passenger vehicles to reduce speed naturally, while their spaced-apart design still improves safety for pedestrians, cyclists, and drivers without slowing emergency vehicles.

Patented Interlocking System

Innovative interlocking construction connects each unit like puzzle pieces, ensuring a secure fit that prevents shifting or movement.

Fully Modular & Customizable

Modular units allow complete customization of length, width, tape color, and the choice of striping or directional arrow designed to fit any roadway requirement.

Eco-Friendly Recycled Rubber

Manufactured from 100% recycled rubber, these speed cushions offer a sustainable traffic-calming solution. Many municipalities qualify for recycling or green-product grants.

Two-Year Manufacturer Warranty

Includes a two-year warranty on speed cushion components when installed according to manufacturer guidelines.

Fast Deflation Time

Each hump features an average deflation time of approximately 50 seconds, ensuring reliable performance and quick recovery after vehicle passage.

“The MUTCD does not contain any provisions regarding where to use or how to design speed rubber humps. From the MUTCD perspective, speed rubber humps are considered to be roadway features, not traffic control devices. However, if a decision is made to implement speed humps on a particular roadway, the MUTCD has provisions about the warning signs (see Section 2C.29) and the pavement markings (see Sections 3B.25 and 3B.26) that are associated with the use of speed humps.”

Frequently Ask Questions

What is a speed cushion?

A speed cushion is a traffic calming device made of several narrow rubber sections placed across a road with gaps between them. A standard passenger car rides over the full width and slows down, while the wider wheelbase of a fire truck, ambulance, or bus straddles the gaps and passes through without slowing, which is why speed cushions are the standard choice on emergency response routes.

How are speed cushions different from speed humps?

A speed hump spans the entire width of the lane, so every vehicle, including emergency vehicles, slows down the same amount. A speed cushion is split into sections with gaps sized for a wider emergency vehicle axle, so fire trucks and ambulances can straddle the gaps and maintain speed while passenger cars still slow to 15 to 20 mph.

Do speed cushions slow down fire trucks and ambulances?

No, that's the specific problem they're designed to solve. The gaps between cushion sections are sized to match the wider axle track of fire trucks and ambulances, so those vehicles straddle the cushions and pass through at normal speed while passenger vehicles are still forced to slow down.

How are rubber speed cushions installed?

Rubber speed cushions install using interlocking modules that snap together on site and bolt to the road surface, no excavation required. A standard speed cushion installation is typically completed within a day, in line with TS&L's 24-hour onsite guarantee.

What size are standard speed cushions?

TS&L's standard speed cushion is 3 inches high, with a footprint built from 18 by 42 inch interlocking modules. Overall width and length are adjustable, from 36 inches up in 18 inch increments for width and 84 inches up in 42 inch increments for length, so the same product can be sized to fit a two-lane residential street or a wider municipal road.

Are speed cushions covered under MUTCD requirements?

The Federal Highway Administration has confirmed that the MUTCD does not classify rubber speed humps or cushions as traffic control devices, but as roadway features. Where a jurisdiction chooses to install them, the MUTCD does have provisions for the warning signs and pavement markings that go along with them, which TS&L accounts for as part of every installation.

Where are speed cushions typically installed?

Speed cushions are most common on streets that double as emergency response routes, residential corridors near fire stations, hospitals, and school zones where slowing regular traffic matters but emergency response time can't be compromised.
