A summer crackdown on drink and drug-driving will begin at midnight tonight with officers on patrol across the county looking for offenders.
Anyone driving erratically or who is suspected of being under the influence of drink or drugs while behind the wheel should expect to be stopped and prosecuted as part of the initiative, named Operation Dragonfly.
Motorists charged with drink or drug driving offences throughout June will have their names published online and made available to the media.
Posters are also being put up across the county at sites where offenders were stopped during the force's Christmas campaign to highlight to potential offenders that they are not safe from being caught if they get behind the wheel while over the limit.
Chief Inspector Natalie Moloney said: "Throughout the year we look for drivers who have been drinking or have taken drugs but from tomorrow there will be extra patrols out specifically focusing on these kinds of offenders.
"There is no excuse for driving while over the limit or after taking drugs and there will be no leeway given to anyone we find doing it.
"I would be delighted if we did not catch one drink or drug driver in June if I could be confident that meant that was no longer an issue in Sussex.
"Unfortunately there remains a hardcore of people who continue to put themselves and others at risk by driving when they are in no fit state to and we will do all we can to get them off the roads to keep people safe."
The force will be using drug testing equipment at each custody suite across the county to see if motorists who have been arrested have cannabis in their systems.
Officers will also tweet about people stopped on suspicion of drink or drug-driving offences throughout June, giving brief details such as when and where the motorists were pulled over.
During June 2013 more than 3,500 motorists were breathalysed and more than 140 people were arrested.
