POLL: Do you think smart motorways should be scrapped?

MPs on the House of Commons' Transport Select Committee have said smart motorways should be halted until their safety can be ensured.

Smart motorways use the hard shoulder as a permanent traffic lane to increase road capacity – but critics say this has contributed to deaths on the roads.

Work to convert the M4 to a smart motorway from Junction 12 (Theale) to Junction 3 (Hayes) is due to be completed next year at a cost of £848m.

But a report from the Transport Select Committee says there is not enough safety data to justify continuing with the plans.
