School District 43 is cautioning motorists to drive carefully and be on the lookout for students heading back to school starting next week.
Many vacations are also coming to an end and more vehicles are expected to be on local roads.
Cheryl Quinton, SD43's manager of communications, said drivers need to give themselves extra time and should make sure they are not rushing during their morning and afternoon commutes.
"We do like to remind motorists, particularly in the first week of school when kids are really excited, to watch out," she said. "There will be a lot more traffic, so please remember to leave yourself a little more time."
She said drivers can get complacent over the summer around schools and should be aware all school zone speed signs are back in effect starting Tuesday. Drivers should also be cautious around schools where construction or road work is taking place, such as at James Park elementary in Port Coquitlam. There also may be disruptions at Eagle Ridge and Aspenwood elementary schools as they install the new modular classrooms to accommodate kids in all-day kindergarten.
"In general, there is a lot of construction around," she said. "Again, motorists not only have to contend with increased traffic but the frustration of detours as well."
In order to reduce the post-Labour Day traffic crunch, the BC Automobile Association is recommending drivers look at commuting alternatives.
Car pools and public transit are a popular way of avoiding commuter stress and, if possible, cycling and walking should be considered as well, the organization said.
