A driver tested positive for cocaine during a random breath test at 4.30pm on March 8.
The 33-year-old man was driving on Macedone Road in Beelbangera when he was stopped by Highway Patrol for a random breath test.
After the test came back positive for cocaine the man was arrested and taken to Griffith Base Hospital for more thorough testing.
If the final results come back positive the man will be charged with driving under the influence of illicit drugs.
In the meantime the man has had his driver's licence suspended.
Griffith Inspector Nick Seddon said this kind of reckless behaviour threatened the safety of everyone else on the road.
"People must take responsibility for their actions when driving on the road," Inspector Seddon said.
"These drugs can remain in your system for a long time and continue to impair your driving ability."
The following day at 11am March 9 two cars crashed on the intersection of Murrumbidgee Avenue and Kookora Street.
A 60-year-old man driving a black Suzuki Sierra failed to give way at the intersection, colliding with a White Holden Commodore.
Police officers breath tested both drivers, but both tests turned up negative.
The driver of the Suzuki Sierra was taken to Griffith Base Hospital for further testing and will be released later.
