Midland Expressway has defended its decision to increase charges
Higher charges on the M6 Toll motorway have come into force following a decision to increase prices for the sixth time in seven years.
It costs £5 for a car, a rise of 30p, and £10 for a truck, a 60p increase.
The company which runs the motorway, Midland Expressway, has said the money would be used to invest in the road's future.
Haulage firms have complained about the cost, saying lorries avoid the road and add more congestion to the M6.
The road links junction four of the M6 at Coleshill, Warwickshire, with junction 11 near Cannock, Staffordshire.
