Which statement about speeding up a commercial vehicle is accurate?

Answer options
- AA jerking motion shows that you are accelerating the right way.
- BOn a slippery road, you should feed the engine more power.
- CSpeeding up roughly can damage the vehicle's mechanical parts. Correct

Abrupt starts strain the engine and driveline and, when you are pulling a trailer, the coupling as well, so speed up smoothly and gradually. A jerky feel is a sign of poor technique, and on slick surfaces extra power just makes the drive wheels spin.
