Driving Safety for Tradies: Managing Fatigue on Long Trips

Driving to jobs is a routine part of work for many electrical contractors, particularly when projects are located several hours away. While long trips are often unavoidable, fatigue behind the wheel can quickly become a serious safety risk.

Understanding when fatigue peaks occur, how to manage breaks, and what employers should consider when apprentices are driving can make a significant difference to road safety.

Industry experts Mick Owar from Primal Recovery and Shawn Miller from The Cars Daily share practical advice for contractors who regularly spend two to four hours on the road.

What is driving fatigue?

Driving fatigue occurs when tiredness reduces a driver’s alertness, reaction time and concentration. Long hours, poor sleep and natural dips in the body’s circadian rhythm can all increase the risk of fatigue.

For tradies travelling long distances to job sites, fatigue can lead to reduced focus, slower responses and an increased risk of microsleeps — brief moments of sleep that occur without warning.

Understanding when fatigue risks are highest and planning trips accordingly can help contractors reduce these dangers.

Key takeaways for electrical contractors

• Fatigue risk increases during circadian low points, typically between 2–6am and 1–3pm.
  
• Mid-morning departures can help drivers stay more alert on long trips.
  
• Regular breaks that involve movement, hydration and natural light are more effective than staying in the vehicle.
  
• Contractors have a duty of care when apprentices or employees are driving work vehicles.
  
• Simple habits such as frequent breaks, vehicle checks and seatbelt use can significantly improve road safety.

When is the safest time to start a long drive?

Fatigue risk often follows the body’s natural circadian rhythm. Starting a long drive during the wrong window can increase the likelihood of tiredness.

“Fatigue risk spikes during circadian low points — roughly 2–6am and 1–3pm,” says Mick Owar from Primal Recovery.

“If possible, avoid starting long drives in those windows. Leaving after sunrise or mid-morning is generally safer than pre-dawn starts. Also factor in sleep debt — even one poor night significantly increases microsleep risk on longer drives.”

Shawn Miller from The Cars Daily agrees that timing plays a role in alertness during longer trips.

“Leaving mid-morning, around 9–10am, helps tradies avoid common fatigue dips in the early morning and after lunch,” says Miller.

“Combined with a good night’s sleep, this timing keeps you alert for two to four-hour jobs and reduces the risk of tiredness-related incidents on the road. Planning around your natural body clock makes long drives safer.”

What should tradies actually do during a rest break?

The common advice is to stop every two hours. However, how you use that break matters just as much as when you take it.

Owar recommends getting out of the vehicle and actively resetting the body.

“Get out of the vehicle. Move. Walk for a few minutes, mobilise your spine, and get natural light into your eyes,” says Owar.

“Hydrate properly — not just water, but water with full-spectrum salts (like a pinch of Celtic sea salt) to support hydration and nerve signalling. If needed, a short eyes-closed rest beats sitting and scrolling on your phone.”

Miller also highlights the importance of stepping away from screens during these breaks.

“During breaks, step out of the van, stretch, hydrate, and get some sunlight if possible,” says Miller.

“Avoid phones or screens — give your brain a complete pause. Even a short walk or light movement helps reset your alertness for the next leg.”

What should contractors consider when apprentices are driving?

When apprentices or younger workers are asked to drive work vehicles, fatigue management becomes part of an employer’s workplace safety responsibility.

Owar says trust and judgement are essential before allowing less experienced workers to handle long drives.

“Beyond legal requirements, you need to build trust and judgement before throwing someone in the deep end,” he says.

“That means knowing their limits, checking fatigue levels, managing shift length, and being willing to delay a drive if needed. Fatigue is a recognised WHS hazard. If someone isn’t fit to drive and you ignore it, responsibility sits with you.”

Miller adds that employers should ensure basic compliance and supervision.

“Employers must ensure vehicles are roadworthy, drivers are licensed, and working hours comply with fatigue laws,” says Miller.

“Brief apprentices on safe driving, monitor schedules, and check they aren’t tired or impaired. Documenting these checks shows a clear duty of care.”

Are caffeine and energy drinks useful for long drives?

Many drivers rely on caffeine to stay alert, but it should not replace proper rest.

Owar warns that excessive caffeine can hide fatigue rather than solve it.

“Too much caffeine exhausts the nervous system and reduces focus, especially when you’re already tired,” he says.

“It masks fatigue instead of fixing it. At that point, the better move is to get out of the car, jump around, move hard for a couple of minutes, get blood flowing, and hydrate with salted water. Movement beats another can every time.”

Miller says caffeine can still play a limited role when used carefully.

“Caffeine can boost alertness in the short term, but overuse can be counterproductive,” he says.

“Too much can cause jitters, reduce reaction time, or affect sleep. Use small doses at the start of trips and combine with hydration and regular breaks.”

What simple habits or tools can improve road safety?

Improving driving safety does not always require expensive technology.

Owar believes simple movement breaks are one of the most effective habits tradies can adopt.

“Stop more often,” he says.

“Even five minutes every hour to get out, stretch, and ‘jiggle the legs’ makes a big difference. Choose music that keeps you alert — not tracks that lull you to sleep.”

He also points to collision warning systems as useful vehicle technology.

“Tech-wise, forward-facing collision warning systems are genuinely useful. Everything else matters less than movement, awareness, and honest fatigue checks.”

Miller highlights several low-cost safety habits.

“Small habits save lives,” he says.

“Seatbelts, a first-aid kit, a dash phone mount, and pre-trip vehicle checks for tyres, lights, and load security all help. Consistently applying these simple measures keeps tradies safer on the road without costly equipment or complicated procedures.”

Frequently asked questions about driving fatigue for tradies

How long should tradies drive before taking a break?

Experts commonly recommend stopping every two hours. However, shorter and more frequent breaks that involve movement and hydration can also help maintain alertness.

What time of day is fatigue most likely?

Fatigue commonly peaks between 2–6am and 1–3pm due to natural circadian rhythms.

Are energy drinks a good way to stay awake while driving?

Energy drinks may provide a short-term alertness boost, but excessive caffeine can reduce focus and mask fatigue rather than solve it.

What should employers consider when apprentices drive work vehicles?

Contractors should ensure vehicles are roadworthy, drivers are licensed, working hours comply with fatigue rules, and apprentices are not driving while tired.

What electrical contractors should remember

Long drives are part of the job for many tradies, but fatigue behind the wheel is a serious safety risk.

Planning departure times, taking meaningful breaks, monitoring driver fatigue and applying simple safety habits can significantly reduce that risk.

For contractors managing teams, ensuring drivers are rested, supported and properly briefed is also an important part of workplace health and safety responsibility.
