MILLIONS of drivers are set to be impacted by a new speed limit being imposed on a crucial UK motorway this month.
The new 50mph speed limit is putting motorists at risk of a hefty £1,000 fine.

Motorists are being warned about the reduced speed limit on the M5 motorway coming into force over the next few months.
Further disruptions are also expected to occur as multiple sets of work take place along the motorway in Devon and Somerset.
They are due to last until February 2026.
Three narrow lanes in each direction will be hit with the new 50 mph speed limit around junction 26 for Wellington.
This is for the majority of the second set of works starting on Monday, October 26.
De-silting of ditches, gully renewal, resurfacing, replacing blocked drainage pipes and fittings, road marking updates, camera survey and proofing are among the works to be carried out.
It involves a £5.9 million programme which aims to improve drainage and alleviate flooding on the verges and carriageway near junction 26.
The National Highways scheme has been tasked with resolving flooding issues and improving safety for motorists on the M5 in Somerset.
In doing so, they will maintain three narrow lanes in each direction with the reduced 50mph speed limit for safety reasons.
The speed limit will be in place northbound from October 28 until February 19.
A similar speed restriction is set to be in place on the southbound carriageway from November 2 until February 11.
Sections between junctions 28 and 30 have also been closed since last month as work is being carried out on the southbound carriageway.
These works are set to last until December, with crews operating on weeknights.
