A woman has died while having s*x behind the wheel with her husband at 50mph. Her husband has been jailed for five years over the horror smash which killed her.

According to The Sun UK, Matthew Notebaert was in the car with wife Amanda on his lap when he crashed.

Cops said the 33-year-old was driving 55mph in a 30mph zone at around 12.30am when they hit a canal bank.

A toxicology report found Notebaert's blood alcohol level was almost twice Florida’s legal limit, and he also had marijuana in his system, Palm Beach Post reported.

In an emotional plea to judge Laura Johnson, Notebaert said: “I miss her more than words can express.”

The court heard the pair had been heading home from a concert after Notebaert bought her the tickets for a Valentine’s Day present in March 2014.

Notebaert was driving when he was pulled over and the couple “got intimate”, Palm Beach Post reported.

His last memory was driving on Southern Boulevard with his wife sitting on his lap.

The next thing he remembered was waking up in the wreckage of the vehicle next to her dead body.

Arrest reports say the SUV flew 30 feet in the air after smashing into the canal wall.

Amanda, the mother of their two now teenage children, died at the scene after hitting her head on the windshield.

Her father Mike Stacey called on the judge to give his son-in-low the “maximum allowable sentence”, according to reports.

He said in court: “You had a responsibility to get your wife home safely.”

Sentencing him to five years behind bars, Judge Johnson said: “You failed your wife, you failed your children and you failed all your family that is here today.”
