In April 2015, the Driver and Vehicle Standards Agency (DVSA) introduced a new headlamp aim test for heavy vehicles. We changed the test following significant research which resulted in a report on the effect of road safety. The report was produced by the Transport Safety Research Centre (TSRC) at Loughborough University.
