Commentary on Sections Part 2 - Vehicles Section 3 – Repairing vehicles on a road
This section makes it an offence to carry out “restricted works” to vehicles on a road. “Restricted works” means:
	works for the repair, maintenance, servicing, improvement or dismantling of a motor vehicle or of any part of or accessory to a motor vehicle;
	works for the installation, replacement or renewal of any such part or accessory.
A person will not be convicted of an offence if he proves that the works were not carried out in the course of a business or for gain or reward. However, this defence is only available where the works did not give “reasonable cause for annoyance” to persons in the vicinity. A person will also not be convicted of an offence where the repairs arose from a breakdown or accident and were carried out promptly or were otherwise authorised.
