UPDATE: Parklands resident Julie Hayward was just dozing off in bed about midnight when she was startled by the noise of a loud crash.
"I just heard this almighty crash and the (house) lights flickered on and off," Ms Hayward said.
She got out of bed and went out the front of her Hibiscus St home to see a few other neighbours had also stepped outside to investigate the noise.
"I just listened because there was no traffic.
"I went walking up (toward Nambour Connection Rd) and sure enough saw the lights blinking on and off."
She said another nearby resident was already at an overturned Holden sedan.
"We looked in and the guy said I don't think we've got a pulse."
"It was awful."
Emergency services were called and rushed to the scene.
"You can't help but feel sad and sick for the family.
"It's playing in my head all of the time."
EARLIER: A man has died in a single-vehicle crash at Parklands, north of Nambour, overnight.
Emergency services were called to the scene on the Nambour Connection Rd shortly after midnight.
A police spokesman said it appeared a Holden sedan had crashed into a power pole support cable before overturning.
The driver and sole occupant of the vehicle, a 42-year-old man from Woombye, was pronounced deceased at the scene.
Police are appealing for anyone who may have seen the incident or the white commodore sedan travelling on Nambour Connection Road to contact Crime Stoppers on 1800 333 000.
Clayton's Towing, who responded to the crash, posted a picture on its Facebook site lamenting the loss of life.
The towing firm has been involved in many public displays and police initiatives to highlight public safety on our roads.
News of last night's fatality comes as Sunshine Coast police continue a week long blitz on factors leading to road crashes, including fatigue.
In Queensland, between 2008 and 2013, more than 15% of fatalities were identified as being fatigue-related crashes. The actual number may be much higher as it can be difficult to identify fatigue as a causal factor.
Research shows that being awake for more than 17 hours is similar to having more than two standard drinks and having a blood alcohol content of more than 0.05.
Keys to avoiding fatigue
Avoid driving at night when your body naturally wants to sleep.
Avoid long drives after work.
Understand whether any medicine you are taking might affect your driving.
