BEST PRACTICE:

G5−5: Improved Warning Lights on Vehicles

DESCRIPTION:

The Missouri Department of Transportation (MoDOT) outfits trucks with a visible strobe type warning lightthat uses a 180−watt output controller to increase the power and visibility of the lights on MoDOT vehicles, compared to previously−used 50−watt bulbs. The strobe light system regulates each output at a constant rate, and it is able to power up to eight outputs with equal intensity. Through field tests travelers indicated that the light was more visible with better recognition, even up to 1 mile away.

REASON(S) FOR ADOPTING:

To increase safety of employees by increasing the visibility of MoDOT vehicles.

PRIMARY BENEFIT(S):

Benefits anticipated are achieving better motorist recognition and better operator visibility. Work zone crashes should be reduced and productivity should be improved.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

Any State vehicle.

STATE(S) WHERE USED:

Missouri
