New Sign Post Specifications - IMPORTANT INFORMATION
Soon there will be new specifications on breakaway sign posts.
Current MUTCD (Manual on Uniform Traffic Control Devices) specifications
state that ground mounted sign supports shall be breakaway, yielding or
shielded with a longitudinal barrier or crash cushion if within the
clear zone. There are more stringent deformation requirements coming -
LESS ROOF DEFORMATION ALLOWED and NO WINDSHIELD PENETRATION FROM
SIGNS AND SUPPORTS DURING A COLLISION ARE ACCEPTABLE.
SOLUTION: SNAP’n SAFE™ Couplers
Designovations, Inc. now offers new technology with the SNAP'n SAFE™
breakaway sign post couplers. Using a vehicle specified in the existing
Report 350, this new technology meets and exceeds the more stringent
damage levels contained in the updated NCHRP Report 350 specifications
for ground mounted sign supports.
Features and Benefits
• Cost Savings - Install or repair sign
posts in half the time with one person.
• Roads are Safer - The sign post will no
longer strike and penetrate the windshield or roof of a vehicle during a
collision.
• No anchors to repair, slash crew exposure
to traffic, and Reduced Liability.
The Manual on Uniform Traffic Control Device (MUTCD section 2A-19)
which is the national standard used for all roads open to public travel,
states that roadside sign supports in the clear zone SHALL be breakaway,
yielding or shielded.
This requirement applies to all roads, whether publicly or privately
owned.

Fatalities: Fatality Analysis Reporting System (FARS) 2000-2004 Final
& 2005 Annual Report File (ARF) Injuries: General Estimates System (GES)
2000-2005
NOTE: The injury and property damage numbers are not actual counts, but
estimates of the actual counts. The estimates are calculated from data
obtained from a nationally representative sample of crashes collected
through NHTSA's General Estimates System (GES).
Estimates should be rounded to the nearest 1,000. Estimates less than
500 indicate that the sample size was too small to produce a meaningful
estimate and should be rounded to 0.
