Drivers caught on video speeding on the M4 in Newport avoid prosecution.

Drivers caught exceeding the speed limit on 50mph speed cameras on the M4 are not prosecuted.

The 50mph speed cameras between junctions 24 and 28 in Newport have been operational since last year in one of the UK’s busiest traffic areas.

Prosecution warnings were supposed to be sent out in the area where a relief road was formerly planned last summer.

The cameras are operational, but “resource constraints” prevent prosecution notices from being issued, according to the Welsh government.

It has now decided to discontinue providing advice letters to drivers and “completely enforce” new 50mph limits on all other highways where they are in effect.

They are as follows:

Between the Wales/England border and St David’s is the A494.

Wrexham’s A483 between junctions 5 and 6.

The A470 connects Upper Boat and Pontypridd in Rhondda Cynon Taf, Wales.

The M4 between Port Talbot junctions 41 and 42.

According to a Welsh government spokeswoman, “Advisory notices were introduced as an interim measure while the new environmental 50mph speed limit was implemented.”

“These notices will be removed with immediate effect in all regions, and full enforcement will be carried out as necessary.”

Following the recommendation of the commission formed in the aftermath of First Minister Mark Drakeford’s controversial decision to scrap the relief road, the average speed limit of 50mph was implemented to alleviate congestion on the M4 around Newport.

According to the commission’s assessment, the M4 at Newport was the fourth most congested section of urban freeway in the country.
