The Snowman is bang on, every driver who works for those listed firms now knows that they will never be pulled over for a roadside check. Traffic planners & management at those firms also know that their drivers will never be pulled over for roadside checks. This will only lead to complacency, wider spread lazy practise and convenient bending of the rules where it suits… “just stick that extra pallet on, no one will know it’s over weight”, “■■■■■■■■ to that broken brake light/low tread, i’ll just crack I won’t get pulled” etc. etc.
In my experience, a lot of these ‘green light’ and now soon to be except firms probably wouldn’t still have green lights if the DVSA weren’t so ■■■■■■■ at the roadside dealing with bent foreign hauliers all the time.
