Only little bit over?!

Police were left shaking their heads after a driver was busted at allegedly more than four times the alcohol limit in Croydon last night.

An automated number plate recognition site was set up on Mt Dandenong Road when the vehicle came to their attention about 9.20pm.

The driver of the vehicle, a 45-year-old Mooroolbark man, returned an alleged breath test of .212.

His vehicle was impounded for 30 days at a cost of $1555 and his licence was immediately suspended for 12 months.

He is expected to be charged on summons with unlicensed driving and drink driving offences.

This impound was part of Operation Compass, the state-wide road policing operation during the high-risk Easter holiday period.

Police are targeting impaired driving, speed, distraction, and fatigue in high-risk areas throughout metropolitan Melbourne and regional Victoria.

Operation Compass concludes at 11.59pm on Monday, 25 April.
