Road Speed Simulator


The Speed Simulator enables you to test Road Speed Limiters in-cab via the tachograph while the vehicle is stationary.

This means you can undertake pre-tests prior to vehicle inspections, so that the vehicle is presented for test with the RSL operating at the required speed. This helps to ensure first time passes at Annual Tests, and saves you time.
