Under hver fri accelerationscyklus skal motoren nå tophastigheden eller, hvis køretøjet har automatisk gear, den hastighed, som producenten har angivet, eller, hvis disse oplysninger ikke foreligger, to tredjedele af tophastigheden, før gaspedalen slippes.
During each free acceleration cycle, the engine shall reach cut-off speed or, for vehicles with automatic transmissions, the speed specified by the manufacturer or if this data is not available then two thirds of the cut-off speed, before the throttle is released.
