The following information is a quideline for applying truck service to the loading dock area to
insure proper design, safety and service to your loading dock area. Apply proper Traffic Engineering design standards
and compliance with local codes.
Property Gates
Suggested minimum width at gates leading into approach roadways is 16' to 20' (4.9m to 6.1m) for one-way traffic, 30' to 32'
(8.7m to 9.3m) for two-way traffic, and 38' (10.7m) if pedestrian walkway is to be included.
Roadway Approach
Trucks should be permitted to drive in rather than back in. Straight-through, "Y" or angle approaches should be considered
depending on traffic volume estimates. If mixed passenger car and pedestrian traffic is involved in the approach, suitable
seperation and safety precautions should be planned for.
Yard Approach
Service roads for one-way truck traffic should be a minimum of 14' (4m) wide...for two-way traffic no less than 26' (7.8m) wide.
if pedestrians are to be accommodated, there should be an additional 6' (1.6m) lane separated from the roadway by a physical
barrier.
If a right angle intersection is required, a 50' (15.2m) radius should be planned for commercial vehicles.
The design of approach roadways should also allow for counterclockwise traffic circulation since it is easier for drivers to make
left-hand turns and to back trailers into a dock from this position.*
