New Brunswick posts 110 km/h on its divided highways, including the four-lane Trans-Canada (Route 2) that crosses the province from the Quebec border to Nova Scotia. Rural roads default to 80 km/h where unposted and urban streets to 50 km/h. Since 2023 the province has layered tough excessive-speeding penalties on top of ordinary fines, with vehicle impoundment starting at 50 km/h over.

About speed limits in New Brunswick
New Brunswick's 110 km/h limit applies to its divided, controlled-access highways, and the province has more of them per capita than most of Canada. Route 2, the fully twinned Trans-Canada, carries 110 km/h from Edmundston through Fredericton and Moncton to the Nova Scotia line, and Route 1 provides a similar four-lane run from the US border at St. Stephen through Saint John toward Moncton. Other arterial highways are typically posted between 90 and 100 km/h depending on design, while collector and local routes step down from there. Under the Motor Vehicle Act, the default where no sign is posted is 80 km/h on rural highways and provincial roads.
Inside cities, towns and villages the default limit is 50 km/h unless otherwise posted, covering residential streets in Fredericton, Moncton, Saint John and the smaller municipalities. School zone limits are posted locally, commonly 30 to 50 km/h during school hours, and amendments to the Motor Vehicle Act standardized how those zones are structured and require the recommendation of a transportation professional before a school zone limit is raised or lowered. Speeding fines carry heightened penalties in school and construction zones when children or workers are present, and police time enforcement to school openings each September, so the start of the school year is the worst time to test the margins.
New Brunswick runs a two-tier excessive-speeding regime introduced through 2023 amendments to the Motor Vehicle Act. Driving 50 to 80 km/h over the limit brings a flat $500 fine, five demerit points and a mandatory seven-day vehicle impoundment; more than 80 km/h over brings a $1,000 fine, six points and a 30-day impoundment, with towing and storage charged to the registered owner. Below those thresholds, ordinary speeding costs three points for up to 29 km/h over and five points from 30 km/h over, and accumulating points pushes drivers toward warning letters, licence review and suspension under the provincial point system.
Enforcement on the open highways belongs to the RCMP, with municipal and regional forces covering Fredericton, Saint John and the Codiac region around Moncton. New Brunswick has no photo radar or automated speed cameras, so tickets come from patrol officers running radar and laser, and the long, quiet stretches of Route 2 are regularly worked by unmarked units; RCMP publicize periodic blitzes that produce more than a hundred tickets in a single operation, sometimes with vehicles towed under the excessive-speeding rules. Winter matters too: the Motor Vehicle Act requires speed appropriate to conditions, and driving the posted 110 km/h in snow or freezing rain can still earn a careless driving charge.
Enforcement
RCMP patrol the Trans-Canada and rural highways, including with unmarked vehicles, while municipal forces cover Fredericton, Saint John and the Moncton area. There is no photo radar in New Brunswick, and periodic enforcement blitzes on Route 2 produce large ticket counts and occasional roadside vehicle impoundments under the excessive-speeding rules.
Tolerance
Traffic on the 110 km/h Trans-Canada commonly flows several km/h over and officers tend to concentrate on larger overages, but nothing is guaranteed and the excessive-speeding thresholds at 50 and 80 km/h over are absolute. In school and construction zones, and in poor winter conditions, expect no slack at all.
Speeding fines in New Brunswick
Ordinary speeding fines generally land in the low hundreds of dollars and scale with speed, with three demerit points for up to 29 km/h over and five points from 30 over. At 50 to 80 km/h over, the penalty is a flat $500, five points and a seven-day vehicle impoundment; above 80 km/h over it is $1,000, six points and a 30-day impoundment, with towing and storage billed to the owner.
Frequently asked questions
What is the maximum speed limit in New Brunswick?
The maximum is 110 km/h, posted on divided highways including the twinned Trans-Canada Route 2 from Edmundston to the Nova Scotia border and much of Route 1 through Saint John. Other arterial highways are typically 90 to 100 km/h.
What is the default speed limit in New Brunswick?
Where no sign is posted, the Motor Vehicle Act sets 50 km/h inside cities, towns and villages and 80 km/h on rural highways and provincial roads. Posted signs override both defaults.
What happens if you are caught 50 km/h over the limit in New Brunswick?
Driving 50 to 80 km/h over brings a $500 fine, five demerit points and a mandatory seven-day vehicle impoundment. Above 80 km/h over, the fine rises to $1,000 with six points and a 30-day impoundment, and the owner pays towing and storage.
Does New Brunswick use speed cameras?
No. New Brunswick has no photo radar or automated speed enforcement, so all tickets are issued by RCMP or municipal officers using radar and laser, often from unmarked vehicles on the Trans-Canada.
