Today was a good day, started at 9am in Woking went to Colnbrook to collect a trailer then to Rochester to get loaded up and delivered to Guildford and then back to Woking. All in 8 hours 50 minutes. First time ever driving a Renault. Caused a bit of commotion on the A320 when stopping at a set of traffic lights I inadvertently knocked a switch which shut down the lorry. Everything went blank, no lights, four ways, couldn't do anything. Thought that the wagon broke down as all day it was showing a 'Fuel filter' problem. Called the yard and the mechanic asked me about the switch, low and behold everything was turned back on. The switch is there as the tractor unit is used to pull fuel tankers, something new was learned today.
