Pop quiz: 1) In highway construction zones, do most fatalities occur A) to the vulnerable workers who are standing in the work zone while thousands of cars and trucks speed by, or B) to the motorists in the cars and trucks that are speeding by?
2) Are most highway construction workers killed by A) being struck by passing motorists or B) being struck by construction vehicles?
If you guessed “A” for both answers, you are correct.
Motorist safety in highway work zones
Highway construction projects pose hazards for drivers and workers alike, but about 85% of the vehicle-related fatalities that occur in work zones each year involve motorists. Lane changes,uneven surfaces, stop and go traffic, driver impatience at delays, unpredictable occurrences, and poor night visibility are all factors that make these zones hazardous. For those who need further incentive for caution than self preservation, bear in mind that 32 states and the District of Columbia double the fine for speeding (or committing other traffic violations) in a work zone. The Governors’ Highway Safety Administration offers a handy state by state chart of work zone traffic laws.
One of the best safety strategies a driver can take is avoidance: seek an alternate route. The Department of Transportation offers national traffic and road closure information to help drivers plan in advance – or drivers can check with state transportation authorities – most offer alerts about major construction projects. For those who can’t avoid a construction route, the Wisconsin DOT offers tips for safe driving in a work zone. The tip sheet notes that work zones requiring special caution encompass more than just highway construction projects. They include emergency vehicles at the side of the road, snowplows, garbage pickups, landscapers and any situation where workers are at risk.
Worker safety in highway work zones
This spring, the NIOSH Science Blog featured an excellent post by David E. Fosbroke about construction equipment visibility. In the post, Fosbroke cites a multi-year study of 844 fatalities at road construction sites. While 73% of these fatalities occurred when workers were struck by vehicles, victims were killed by construction equipment at least as often as by passing motorists. And of the incidents when workers were killed by construction equipment, at least 50% of those fatalities involved vehicles backing up.
To help prevent such fatalities, NIOSH offers downloadable blind area diagrams of of 38 pieces of construction equipment and 5 pieces of mining equipment. These diagrams map out the area around a vehicle or piece of equipment that cannot be seen from the operator’s position. The post explains this and other issues related to highway construction safety – including some good observations in the comments section.
For additional information, The National Work Zone Safety Information Clearinghouse provides comprehensive information to improve motorist, worker and pedestrian safety in roadway work zones. Resource include links to related sites and training resources.
