Line painting season in Durham Region

WHITBY, ON June 05, 2017

The Regional Municipality of Durham, Works Department would like to advise residents that roadway line painting is now underway, and drivers should exercise caution when approaching these vehicles.


Line painting season runs until October. Operations are typically underway on weekdays between 9 a.m. and 3 p.m. or overnight.


The Region is responsible for pavement markings on more than 2,000 lane kilometres in Durham, including all Regional roads and many municipal roads.


Line painting trucks operate at reduced speeds to ensure the proper application of road paint. Drivers are reminded to exercise caution when approaching line marking operations. Please keep a safe distance back, and do not attempt to pass.

Follow-up trucks travel behind the line painting trucks to act as a buffer and allow sufficient paint drying time. Drivers are asked to stay behind the follow-up truck, be patient, and seek an alternate route when possible.

Because line paint contains glass beads to make it reflective, driving on fresh line paint can cause damage to vehicles or compromise the quality of the reflective road lines.


Line markings are used to define lanes and guide traffic on roadways, as well as to provide guidance to drivers and pedestrians about safe practices.
