Managing traffic flow with a keep left sign
The value of a keep left sign is that it removes a decision. On a shared site road, in a car park aisle or on a pedestrian route, the accidents happen where two people each assume the other will move. Setting a consistent direction means nobody has to negotiate. Place it where the flow begins rather than where the conflict happens - at the entrance, at the head of the aisle, at the point where a two-way route becomes one-way. Repeat it at intervals on a long run so a driver who joined halfway still gets the instruction. Two honest limits: this is a private-site sign with no legal authority on a public road, where regulatory signs are installed by the road authority; and signage alone does not separate people from vehicles. Where the risk is serious, physical separation, speed control and a traffic management plan do the real work.
Common uses
Car parks and aisles, warehouse and yard roadways, construction site access, loading areas, pedestrian walkways and event traffic management. Pair it with a no entry sign for one-way routes or no parking for restricted bays, or browse more fire and safety equipment at MediBC.
Keep Left Sign FAQs
Where should a keep left sign be placed?
Where the flow starts rather than where conflicts occur - the entrance, the head of an aisle, or where a two-way route becomes one-way. Repeat it along a long run so late joiners still get the instruction.
Does it have legal force?
On private property it sets the site rule and supports your traffic management. It is not a regulatory road sign and carries no legal authority on a public road, where signs are installed by the road authority.
Is a sign enough to keep pedestrians safe?
No. Signage informs but does not separate. Where vehicles and people share space, physical separation, speed control and a traffic management plan do the real work, with signage supporting them.
What size should a vehicle-facing sign be?
Larger than a pedestrian sign. This 450 x 600mm size suits a site roadway or car park. Check it reads from where a driver must act, at the speed they will be travelling.
Can it be mounted outdoors?
It is rigid plastic suited to sheltered outdoor positions on a post, fence or wall. For full exposure over years, ask us about UV and outdoor suitability before ordering.
