Heavy vehicles are licensed in Saskatchewan according to their gross vehicle weight. Weight limits for both axle weights and gross weights are established separately under the act to protect highways and bridges. All drivers should be aware that these are separate requirements and that they cannot exceed a registered weight or a highway weight limit.
Saskatchewan has established different weight systems for various classes of highways. These are referred to as the Primary Highway System, the Secondary Highway System and the Municipal Highway System. Primary highways allow heavier gross weight limits than secondary highways.
