Nova Scotia Oversize Load Permits, Regulations & Axle Rules

Most oversize moves in Nova Scotia run daylight only. Loads over 4.27 m high are off the road from sunset to sunrise. The two metro areas add curfews on top of that: in Halifax Regional Municipality and Cape Breton Regional Municipality, permitted loads are off two-lane and multi-lane highways from 7:00 a.m. to 9:00 a.m. and 4:00 p.m. to 6:00 p.m. The weekend taper is firm: nothing after 3:00 p.m. Friday, and nothing after noon on Saturday, Sunday, or any public holiday.

Ten stat holidays close the road: New Year's Day, Good Friday, Victoria Day, Canada Day, Natal Day, Labour Day, Thanksgiving, Remembrance Day, Christmas Day, and Boxing Day. Adverse weather or reduced visibility stops a move. Drivers must pull up before every underpass, confirm clearance, then creep through.

Exceptional moves invert all of that. They run 12:01 a.m. to 6:00 a.m. only. Anything wider than 5.5 m is narrowed further to 3:00 a.m. to 9:00 a.m. on Sundays exclusively.

A tractor semi-trailer hauling poles, pipe, or material that cannot be broken down earns an overall length of 25 m instead of the standard 23 m. The same 25 m applies to B-train and pole-trailer configurations. Auto carriers get a stacked relief: up to 4.30 m high when loaded (the general ceiling is 4.15 m) and up to 25 m long, as long as the driver confirms clearance at every overpass.

Boats get handled case by case. A hull wider than 5.5 m moved locally can have the police-escort requirement waived by the Area Manager, who also sets the timing directly. Implements of husbandry are exempt from dimensional limits altogether, though anything over 2.6 m wide needs a slow-moving-vehicle sign and warning flags or lights, and above 4.27 m wide a pilot vehicle is required when the load crosses the centre line. Snow-clearing and road-building equipment operating in a construction area are exempt outright.

Nova Scotia calls its top tier an Exceptional Move. A load qualifies the moment it exceeds any one of: width over 5.49 m, length over 30 m, height over 4.88 m, or gross vehicle weight over 69,800 kg. The weight variant is a special-circumstance permit with no annual option. Plan on 10 working days to process.

Above the entry thresholds sit hard escalation gates. Width at 7.9 m or greater requires District Director approval for every district the route crosses. Length over 40 m needs Transportation and Infrastructure Renewal staff sign-off. Width over 9.1 m is not permitted on any road in the province.

Insurance is $2,000,000, with the Crown named as co-holder. Anything outside the standard procedure needs Executive Director of Maintenance and Operations approval before review even begins.

Nova Scotia builds route review into the permit application itself. The carrier must submit a routing that lists every road in travel order by name, with the distance on each segment and the civic addresses of origin and destination. That approved route attaches to the permit and rides in the cab.

Bridges govern the heavy decisions. Conditions can bar steel-truss crossings off the 100-Series network, cap speed at 45 km/h, restrict a span to one vehicle at a time, or force a detour where interchange ramps allow one. On 100-Series highways one lane stays open throughout; because most bridges are too narrow for that, moves typically wait for a break in traffic and cross with nothing else on the span.

Loads over 4.88 m high must secure written clearance from Nova Scotia Power, Bell Aliant, and the cable companies before the permit issues. Outside-procedure moves require a full Traffic Management and Physical Move Plan submitted at the applicant's cost before any review begins, and review does not guarantee a permit.

Nova Scotia runs a genuine sworn-officer tier. When police escort is required, it must be an RCMP or municipal officer in a marked car. The mover covers all costs, and written confirmation from the escorting force must land before the permit is released.

The province-wide trigger is width of 6.7 m or more, or length over 40 m. A width matrix then determines the response. On undivided controlled-access highways, a load over 7.9 m wide is permitted only with police escort. On other roads, a load over 6.7 m wide requires either a full road closure or police escort plus detour. Loads between 5.5 m and 6.7 m wide are handled by a civilian scout vehicle instead.

Specific structures add their own requirements. Crossing the Canso Causeway means contacting the RCMP 24 hours in advance to set the time. Closures at the Seal Island Bridge or the Canso Causeway require an RCMP escort or full traffic control. Police or traffic control is also required at any intersection where the load forces cross-traffic to stop for a turn.
