Timing is everything in sex, but for one couple it ended in a bit of a buzz kill.

Richmond RCMP tweeted Wednesday they had stopped a moving vehicle after spotting a couple having sex while driving.

Cpl. Dennis Hwang said an officer noticed something unusual about a car driving on Number 5 Road and Westminster Highway on Tuesday evening.

"There were two people where there would have been one traditionally — I'm not going to describe that in any more detail. You can use your imagination," he said.

"The driver was having trouble keeping his car straight."

Police joked that while the male driver was definitely distracted, no electronic device was found. The driver now faces a $368 ticket for driving without due care and attention and a $167 fine for a seatbelt violation.

Hwang also said it took longer than usual to produce a driver's licence and registration.

"They were a bit embarrassed and you might say this ended in a buzz kill of sorts."

Hwang says that in 19 years of police service, he's never seen anything like this.

"It's obviously incredibly dangerous for a number of reasons," he said, adding that the distracted driver could wind up in an accident and airbags are not meant to be deployed when two people are in the same seat.

"Find an appropriate and private place to have sex — not while driving."
