Wheel Stops and Bollards
Bollards and wheel stops are not explicitly required by ChargePoint. However, ChargePoint recommends
these best practices and considerations when designing the site:
Permanent bollards or wheel stops must not encroach upon the clearances listed in the clearance
l
diagrams in this section. Removable bollards are allowed if service personnel have the ability to
move them as needed.
Where permitted by code, wheel stops are preferred over bollards for head-in or back-in spaces.

Wheel Stops
When using wheel stops, consider the average vehicle overhang distance for the largest type of
l
vehicle (passenger, bus, etc.), as well as leaving space for the driver to walk up and access the
station.
Position wheel stops to actively block at least one wheel, without presenting a trip hazard to
l
pedestrians walking between vehicles.

b. Cable reach radius: 3.76 m (148 in)
c. Recommended distance for walk-up access: 609 mm (24 in)
d. Recommended distance between wheel stop and staton: 1371 mm (54 in) for passenger
vehicles
