Car drivers taking the ferry from Portsmouth to St Malo need to be ready for a new legal requirement from July 1st.
Answering a query from a reader in the Portsmouth News, former trading standards officer Richard Thompson confirmed that from the start of next month, drivers are required to carry at least one breathalyser kit so they can check their own blood alcohol levels.
He noted that the limit in France is 0.05 per cent, lower than the 0.08 per cent figure for the UK.
Failure to carry one can incur a small spot fine, although he noted these will not be levied until November.
Mr Thompson revealed that such kits can be obtained at ferry terminals for £2 or less.
Many people will be tempted to drive in the eurozone on holiday as a recent Post Office study has revealed the relative cost of fuel has fallen significantly in the last few months as Sterling has gained in value against the euro.
