Local police in are issuing a plea to tractor drivers to pull over, of face a possible £5,000 fine, following complaints from irate motorists.

Tractor drivers are being urged to pull over, where safe, if they have a queue of vehicles behind them, following a number of complaints from motorists of delays caused by slow-moving agricultural vehicles failing to yield.

Inspector Mark Davies from the Road Policing unit said: “A number of people have contacted Dyfed-Powys police to complain about this recently, so now is a good time to remind all drivers of tractors and other slow-moving vehicles of the need to comply with the law in respect of driving without due consideration for other road users.

"A few tractor drivers will travel slowly along main roads, towing long, laden trailers and not give other vehicles the opportunity to pass. This causes a long snake of cars behind the tractor. Driver frustration then sets in, making impatient car drivers take extreme risks trying to overtake.

"The police recommendation to slow-moving vehicles is to pull over, where it is safe to do so, and make use of lay-bys, when you have six or more vehicles behind you."

Police say the Highway Code states drivers must not hold up a long queue of traffic, especially if they are driving a large or slow-moving vehicle.

Tractor drivers are also urged not to pull over where there are double solid white lines and would mean passing cars crossing those lines.

Insp Davies added: "Some staff on farms who drive tractors and slow moving machinery, particularly migrant workers from overseas, may be unaware that failure to pull over when you have a long queue of traffic behind you could constitute an offence of inconsiderate driving.

"The offence could earn you three to nine points on your licence and a fine of up to £5,000. We would urge farm owners to ensure that staff are aware of the law and they should pull over where necessary and safe to do so.”
