Wheel Stoppers and Wheel Chocks: Keeping Vehicles Safe and in Place

30 October, 2026 | Admin

Short answer: Wheel chocks are wedge-shaped blocks
placed against vehicle tyres to stop them rolling, especially at loading
docks, workshops and on slopes. Wheel stoppers are fixed or portable
stops for parking bays that limit how far a vehicle can move forward or
back. Choose the product by vehicle weight, tyre size, surface and how
often it will be used.

Wheel chocks

A chock sits in front of or behind a tyre and uses a wedge shape to
stop the wheel from rolling. They are used at loading docks to prevent
trailers from moving during loading, in workshops during maintenance and
on slopes. They are also used for aircraft, trailers, and heavy
equipment, although those need specially designed chocks.

Material. Polyurethane chocks are tough, grip on
many surfaces, resist oil and weather and last longer than rubber or
wood. Rubber chocks are cheaper and grip well. Metal chocks can be
strong but may slide on smooth floors. Choose the material that suits
the surface and the weight.

Wheel stoppers (parking
stops)

A wheel stopper is a block fixed to the ground at the end of a
parking bay to stop a vehicle from moving too far forward. They protect
walls, bollards and pedestrians, and mark where to stop. They are made
from rubber, recycled plastic, concrete or other materials, with bolts
or adhesive to fix them to the surface. Bright colours and reflective
strips help visibility.

Choosing a wheel chock

Tyre diameter: a chock must be tall enough to stop
the wheel; a bigger tyre needs a bigger chock.
Vehicle weight: heavier vehicles need heavier,
stronger chocks.
Surface: concrete, asphalt, oily floors or ice;
grip underneath matters.
Use: dock or workshop; handles, ropes or chains
make chocks easier to place and retrieve.
Pairs: use chocks in pairs, on both sides of a
wheel where required by your safety procedure.

Choosing a wheel stopper

Length and height: match the vehicles that will use
the bay.
Material: rubber for general use, concrete for
permanent, heavy areas.
Fixing: bolts or anchors for concrete or
asphalt.
Visibility: bright colour or reflective
strips.
Drainage: gaps or channels in the base so water can
drain away.

Safe use

Always follow your site’s safety procedure for chocking vehicles,
including which wheels to chock and when. Chocks are one layer of
protection and do not replace the handbrake, engine off or dock locks
where they are required. Inspect chocks for wear and damage, and replace
cracked or worn ones.

Common mistakes to avoid

using a chock too small for the tyre
placing a single chock on a slope
using worn chocks that slide on the floor
fixing parking stops with weak fixings that pull out
treating chocks as the only means of securing a vehicle
