People who drive under the influence of drink or drugs are being targeted by police.
The four-week campaign starts this weekend with officers doing extra road patrols to look out for dangerous driving.
The campaign is designed to reduce the number of crashes and injuries caused by people who are over the drink-drive limit or who are on drugs.
In 2011 there were 750 casualties caused by road accidents where at least one driver was over the drink-drive limit, according to police figures.
Officers say they want to make motorists more aware of the dangers as people tend to go to more social events during the summer.
Inspector Ian Martin said: “Our commitment to dealing with drink and drug drivers lasts throughout the year. This four-week initiative provides us with the opportunity to remind the public of the dangers of driving under the influence or drink or drugs.
“During the summer months there are many social events such as barbecues for family and friends or larger organised events such as town shows or village galas. All are perfect opportunities to socialise in relaxed surroundings and many people will take the opportunity to have an alcoholic drink.
“However it is important to remember that the measures of alcoholic drinks consumed at social events can be significantly more than pub measures. Unfortunately, people can get caught up in the moment and unintentionally, or otherwise, over-indulge in alcohol.
“Whatever the occasion, as responsible individuals, we all have a duty to consider the amount of alcohol we consume if we intend on driving. Drivers must consider that, even if you make alternative arrangements to get home after an event, you could be over the limit the next day, depending upon the amount you have had to drink.
“The effects of alcohol do not wear off immediately and drivers must be aware of this if they intend driving the following morning. Make sure you do not get caught out.”
Illegal drugs, as well as large doses of prescription drugs, can also impair driving ability, Inspector Martin said.
Justice Secretary Kenny MacAskill said: “The message is clear: if you choose to drink or take drugs and drive, you choose to lose your licence.
“Scotland takes a tough stance on drink and drug driving. If you risk it you will get a driving ban, a large fine and a criminal record, and you could face a prison sentence and lose your vehicle for good.
“One in nine deaths on Scotland roads involve drivers who are over the legal limit. Awareness campaigns such as this one are vital to get the message through to the small minority who still choose to get behind the wheel after having too much to drink despite all the advice.”
