Drinking and the morning after - that was the message driven by welsh police forces ahead of the recently launched All Wales Summer Anti Drink/Drugs Driving Campaign.
During the month long campaign, a total of 15,485 breath tests were administered.
In the Dyfed-Powys Police force area 5,535 tests were conducted with 88 (1.6%) testing positive.
South Wales Police's ACC Jon Stratford said: "The four Welsh forces have been increasing the pressure this summer to deter people from driving while under the influence of alcohol and drugs – especially late into the night during warm summer evenings. Although a total of 358 arrests for drink and drug related offences during this campaign are alarming, it highlights our collaborative commitment to educate motorists and enforce the law.”
Susan Storch, Road Safety Officer for Dyfed Powys Police said: “We as drivers must take responsibility behind the wheel and not drive while under the influence of alcohol and/or drugs (including certain prescribed medicines); doing so will significantly decrease our reaction times despite possibly ‘feeling’ alert.
“We will continue to work with our partners in driving home the anti-drink/drug driving message as no amount is safe to take before driving; the choice is simple drink or drive not both.”
