so yes it does need updating, most tractors have airbrakes now and can stop faster than a car at 30 mph. possibly a cause for either the nfu or fw to take up????
I'm a firm believer in letting sleeping dogs lay. We do a fair bit of road work, hauling livestock and silage between farms. The local police don't take much notice and that's fine by me.
If the law is updated you can bet your bottom dollar that it'll involve a special driving license, HGV spec brakes and lighting, tacho's and possibly even using derv instead of red. I think the longer we can avoid this the better. The way forward is for farmers to act responsibly by having adequate braking, lights that work and drivers that can handle the task.
