Road remains the main mode for freight transport with increasing commercial vehicle loads along the time. Ageing bridges are used beyond the initially designed lifetime. Therefore, highly overloaded trucks may cause severe damages and bridge collapses. Bridges on secondary roads are the most exposed because of less maintenance. A bridge collapse rarely occurs under the first high overload. Truck drivers use bridges above their load limit, either by ignorance, or to shorten their route. While nothing wrong happens, they cross them again and again with higher loads, despite of the displayed signs on posted bridges. The strategy proposed to mitigate large overloading consists installing weigh-in-motion (WIM) systems to detect potential offenders and to deliver admonition by the relevant authority. Such preventive measures, where criminal offenses may be invoked, could be easily implemented and quite effective. A relevant publicity, may dissuade the truck operators and save several bridges and lives.
