More than 7,500 motorists across Europe failed alcohol breath tests in a single week, according to an operation carried out by the European Traffic Police Network (TISPOL) in 21 countries.

The operation was undertaken to enforce drink-driving regulations, enhance road safety and warn drivers about the risks of drink-driving.

The operation, conducted between June 7 and 13, saw 422,181 drivers tested for both drink- and drug-driving, and 7,699 alcohol and 561 drug offences were reported.

TISPOL chief superintendent Pasi Kemppainen issued a warning to drivers about the risks of driving while under the influence of alcohol or drugs, especially during the summer months.
