The government monitors, controls and issues permits for the movement of all commercial vehicles, including oversize and overweight vehicles. This helps to ensure safety and minimize inconvenience to the travelling public, as well as reduce damage to roads. Identifying and removing unsafe vehicles from the road can prevent vehicle failure on Alberta's highways and reduce collisions that may result in injuries or death. Through monitoring and enforcing safety standards, Alberta Transportation aims to keep the province's highways safe for all road users.

Commercial vehicle licensing

Alberta Transportation provides registration information for commercial carriers that are based in Alberta and travel out-of-province. Rather than obtaining and paying for more plates and registration in each jurisdiction, prorated fees are calculated by the percentage of total distance travelled within each jurisdiction.

Oversize/overweight permits

Alberta Transportation establishes maximum vehicle weight and dimension limits to preserve highway infrastructure and to ensure the safety of the travelling public. This includes legal limits for any registered vehicle for travel on any public road, as well as the provision for movement of oversize loads under permit.
