Lets just hope no-one breaks down...
This will lead to drivers being allowed to use the hard shoulder on some of the busiest stretches of motorways.
Under the plan, drivers will be able to use lanes traditionally reserved for the emergency services and broken-down vehicles. They will be able to drive at 50mph in areas where jams are most common.
But these 'extra lanes' will only be open during peak periods and they will have new emergency lay-bys at regular intervals.
The government believes the plan will cut average journey times on the most congested motorways by up to a quarter.
Hard shoulder driving is well established in some European countries, including Germany and the Netherlands.
The first routes to benefit are expected to be parts of the M6 and M1 and the initial speed limit of 50mph may be increased.
