Maximum clearance bars are critical for underground parking facilities to prevent damage to concrete structures, sprinkler systems, and other piping or ducting that high vehicles can hit.
It’s crucial that clearance heights are properly calculated for display on signs and bars to give over-height vehicle operators ample warning to find an alternate route and avoid colliding with the overhead structure. Accidents involving an overhead structure can cause serious property damage, as well as block traffic flow.
Maximum clearance bars and signage can take on a variety of forms:
- Plastic or aluminum hanging bars
- Soffit mounted signage
- Specific warnings (no trucks allowed)
- Metric and Imperial vehicle height limits
- Exit Only or Entrance Only restrictions
