Beating Summer Fatigue — On the Road and On the Job

This month’s focus is fatigue. Summer brings vacations, family activities, travel, and schedule changes, and while those are a good thing, they disrupt sleep and leave us running on less rest than we realize. For crews spending long, hot days on the roadway, that matters: fatigue affects concentration, reaction time, and judgment — the very things that keep us safe in a live work zone.

Why Fatigue Matters. Fatigue is more than feeling tired. It can impair performance in ways similar to alcohol — reduced hazard awareness, slower reaction times, poorer judgment, and more errors and near misses. In our line of work, a split-second lapse near live traffic is the difference between a normal day and a serious incident.

Common Summer Fatigue Factors. Late nights and early mornings, long-distance travel and time-zone changes, more outdoor activity, busy family schedules, high heat and dehydration, and picking up extra hours to cover for coworkers on vacation all stack up this time of year.

Watch for the Warning Signs — in Yourself and Your Crew. Frequent yawning, difficulty focusing, irritability or mood changes, forgetfulness, slower response times, and increased mistakes. If you notice these in a teammate, say something — that’s Understanding and Communication in action.

Managing Fatigue. Aim for 7-9 hours of quality sleep and keep a consistent schedule, even on weekends. Stay hydrated: dehydration alone drives fatigue, headaches, and lost focus, so drink water steadily throughout the day, especially in the heat. Use your scheduled breaks to actually rest, stretch, and get fresh air. After a long trip or holiday, give yourself time to recover before taking on demanding tasks.

Heat & Air Quality. High temperatures also raise ozone and particulate levels, and air-quality advisories often ride along with the heat. When you are working outdoors all day, check the Air Quality Index at airnow.gov and take heat and air quality seriously — they hit hardest for anyone with lung issues, but poor air affects everyone’s stamina and focus.

Off the Clock — Fireworks & Burn Safety. With the Fourth of July, keep a kid-free zone around grills and fire pits, never leave cooking unattended, and keep sparklers away from young children (they burn near 2,000°F). Light fireworks one at a time and back away, never try to re-light a dud, and keep water close by.

Bringing It Back to the Work Zone. Every one of these comes back to the same fundamentals: show up rested, stay alert to changing conditions, keep hydrated, and speak up the moment you notice fatigue in yourself or a teammate. A rested, focused crew is a safe crew. Let’s finish the summer strong and get everyone home safe.
