Charging hauliers to enter a clean air zone in Bristol will put firms at risk, warned the Road Haulage Association.

All lorries face bans from a number of main roads and pre-Euro VI trucks will face £100 daily charges in plans Bristol City Council is submitting to the Government.

But the Association warned that the charging scheme will force firms with lorries registered as late as 2013 to choose between prematurely replacing their fleets, paying the crippling charges or going out of business
