PCV work is a different job to haulage
Driving a coach is not driving a lorry with windows. Every input you make is felt by up to fifty-three people standing, sitting, drinking coffee or asleep. Smoothness stops being a nicety and becomes the core skill — braking early and progressively, taking roundabouts on a single flowing line, and pulling away without anyone reaching for a handrail.
The customer-facing side is real too. A coach driver handles luggage, timings, tachograph compliance, breakdowns, unhappy passengers, school groups and — on tour and private-hire work — the entire reputation of the operator. Employers hire for temperament as much as for driving.
In exchange, PCV work tends to be more sociable than haulage. Service work is shift-based but usually local. Private hire, school contracts, rail-replacement and tour work all offer variety, and many drivers move between service and coach work over a career.
