Portable safety barriers
A barrier either guides traffic or stops it, and the difference decides what you are allowed to use next to workers. These guides compare plastic, water-filled, concrete and steel barriers by weight, test level and price.
Plastic and concrete barriers
- Portable jersey barriers
Plastic, concrete and steel compared, with a weight calculator.
- Water-filled barriers with fence
Filled weights, wind, pedestrian rules and a count calculator.
The rules behind these guides
- AASHTO MASH
- crash test levels (TL-1 to TL-6) for barriers that must contain a vehicle
- MUTCD 6K.10 and 6M.02
- longitudinal channelizing devices versus temporary traffic barriers
- FHWA eligibility letters
- which crash-tested barrier models are eligible for federal-aid reimbursement; most state approved lists build on them
