  • Height: 4.15 m
  • Length: B-train 27.5 m, combination 23 m, single unit 12.5 m

Permits and fees

  • Over-length / over-width permit (oversize): $15
  • Overweight multi-trip (annual) (overweight): $66 per 1000 kg over limit (min $66).
  • Overweight single-trip (overweight): $57 base + $0.05 per km.

Travel restrictions

  • Over-width loads travel by day. Loads wider than 4.45 m generally may not travel at night; loads 3.85-4.45 m travelling at night require lead and trail escorts. The escort counts on this page are the daytime, two-lane case per the Weights and Dimensions Administration Manual (W&D AM 901 / Policy 801); multi-lane and divided highways may need fewer escorts.
  • Spring road bans reduce allowable axle weights on designated highways; typically start first week of March, last 2-6 weeks, and can change on 48 hours notice. Routes/%/dates from the seasonal Ministry order.
