Standards for pavement markings in Ontario are defined in the Ontario Traffic Manual. The Works Department maintains the line markings on all Regional roads and many of the municipal roads within the Region of Durham. Several years ago, our line painting operation converted to water-based paints with low VOCs in an effort to decrease the impact to the environment.

centre line

Yellow centreline and white lane line markings are generally painted once a year on Regional roads.

Newly constructed and resurfaced roads are marked as soon as possible after paving is complete, although there may be delays due to weather or ongoing construction activities. Care should be taken in unmarked areas.

Intersection markings (stop bars, crosswalks and arrows) are applied using a special epoxy plastic material. This material is far more durable than paint and can better stand up to the extreme wear these markings are subject to. We also use this material for centreline and lane line markings on high volume roads when they are resurfaced. Depending on traffic volumes, plastic markings have a lifespan of five to ten years.

The Works Department paints approximately 1,700 kilometres of line on Regional roads annually, and another 300 kilometres of line for the local municipalities – totalling 2,000 lane km. Line painting season uns from May 1 until mid-October. Operations generally take place between 9 a.m. and 3 p.m.

Line painting involves one paint truck, which travels with one or two follow-up trucks, which act as a buffer to keep traffic back, allowing the new lines to dry before they are driven over. On an average hot, dry day in the summer, dry time for road paint is approximately three to four minutes; however, this number increases with factors such as temperature and humidity.

When approaching a line painting operation, it is recommended that you wait until the line painting truck finishes painting the section of road on which it is travelling. The sections are intentionally kept short for the purpose of allowing motorists the opportunity to pass at the next major cross street. Paint trucks must operate at low speeds of 10 to 20 km per hour in order to paint the lines effectively. Stay behind the follow-up truck, be patient, and seek an alternate route if possible.

Tracking marks

Drivers who pass either the follow-up or line painting truck, risk damage to their vehicles and the new road markings. A common sight on freshly painted roads is "tracking", caused by impatient motorists passing the paint truck. Driving on fresh paint can compromise the quality of the reflective paint on the roadway, which can make it less visible.

Driving on fresh paint can also cause extensive damage to your vehicle. Because road paint contains glass beads to increase its reflective properties, it is not easily removed from the vehicle. If your vehicle is marked by line paint, it is recommended that you use a pressure washer on the affected areas immediately. If you get paint on your vehicle, please contact (905) 666-6257. Please note, the Traffic Operations Centre does not remove paint from vehicles.
