A suspension monitoring system 100 for a heavy goods vehicle comprising a trailer and a tractive unit is described. The system comprises a suspension height indicator 110 that comprises a bracket 115 configured to couple to an axle 15 or chassis 20 of a trailer; and a member 120 coupled to the bracket, the member extends away from the bracket. The monitor comprises a sensor 150 configured to couple to a chassis of the trailer; and a processor communicatively coupled thereto. A power source supplies power. The sensor is configured to sense the position to monitor the height of the suspension relative to the axle; and the processor is configured to determine when the height exceeds a pre-determined limit and alert a user. The power source supplies power independent from power supplied from the tractive unit, allowing the suspension monitoring system to operate when the tractive unit is electrically decoupled from the trailer. The sensor may be an object sensor or light sensor. The power source may be a rechargeable battery powered by renewable energy.
