Wild temperature swings have created a bumper crop of potholes across the state's highways. For IDOT workers, who attack the problem like a light infantry unit, there are clear dangers patching those potholes. Kelsea Gurski with the transportation agency, says motorists should look out for patching crews, noting that you won't have the benefit of the kind of barricades and other warnings tied to construction work zones.

Gurski says the rules are the same as any work zone.

Last week in Jacksonville, three IDOT workers were injured when a wayward driver struck an IDOT worker and an IDOT vehicle with two employees inside. The worker struck outside the vehicle was in critical condition but has since been upgraded to fair.
