Weight limitPeru
1. Weight limit
A weight limit prohibits vehicles or vehicle combinations whose mass exceeds the value shown from entering or passing a road section, bridge, tunnel or other structure. Depending on local law, the restriction may concern the vehicle’s actual loaded mass, maximum authorised mass or load on an individual axle.
Drivers must know which type of mass the sign refers to and must include the vehicle, passengers, cargo and any trailer where required. A vehicle that exceeds the limit must use another suitable route.
Does every weight-limit sign measure the same kind of vehicle weight in Peru?
No. Peru’s sign manual distinguishes maximum weight per axle (R-31) from maximum gross vehicle weight (R-32). Check the actual sign; those are different measurements.

Do cargo and trailers matter for a posted weight restriction in Peru?
Yes. Check the loaded vehicle or vehicle-and-trailer combination and its axle loading against the actual restriction. Peru’s manual distinguishes maximum weight per axle from maximum gross vehicle weight; the empty towing vehicle’s weight alone does not settle compliance.

What should you do if your vehicle exceeds a bridge weight limit in Peru?
Do not drive onto the bridge. Follow the signed alternative route and check the vehicle’s gross and axle loads as applicable. A general heavy-vehicle permit does not automatically authorise crossing every restricted bridge.
