Stopping is part of the job. A good superintendent would rather wait ten minutes for a spotter than deal with a backover, a rollover or a line strike. Stop and speak up when you see any of these:
Many general contractors give everyone on site, including subcontractors and delivery drivers, stop work authority: the right to stop a task they believe is unsafe without being punished for it. It is a company or project policy, not a federal OSHA rule, so ask about it at check-in and learn who to call when you use it.
OSHA says you may refuse work when all of these are true: where possible, you asked your employer to fix the danger and it did not; you believe in good faith that an imminent danger exists; a reasonable person would agree there is a real danger of death or serious injury; and there is not enough time to fix it through normal channels, such as an OSHA inspection. Complaints about retaliation must be filed with OSHA within 30 days. (OSHA, right to refuse)
Truck drivers have a second protection. The Surface Transportation Assistance Act (STAA) protects drivers who refuse to operate a commercial motor vehicle, which generally means 10,001 pounds or more. It covers two cases: when operating the truck would actually violate a federal safety rule, and when the truck’s unsafe condition gives you a reasonable fear of serious injury to yourself or the public. In the second case, you must first ask your employer to fix the problem. STAA complaints must be filed within 180 days. (OSHA, STAA fact sheet; OSHA, STAA desk aid)
This article is general information, not legal advice. State-run OSHA plans, union contracts and company policies can add rules of their own.
What should a truck driver check before entering a construction site?
Call ahead for the gate, a site contact, the traffic plan and the PPE rules. Then stop short of the gate and look at the ground, overhead lines, trench edges, people on foot and your way out. Agree on signals with a spotter before you back in, and walk the route if you have never been there.
Does a dump truck need a spotter to back up on a job site?
OSHA’s construction rule says a vehicle with an obstructed view to the rear can back up only if it has a reverse alarm loud enough to hear over the site noise, or an observer signals that it is safe. Many sites require a spotter anyway. Agree on hand signals before you move, and if you lose sight of your spotter, stop.
How close can a dump truck get to overhead power lines?
Keep a raised dump body at least 10 feet from power lines, and farther from higher-voltage lines. If you cannot keep that distance, dump somewhere else or ask for the utility to de-energize or insulate the line.
What should a driver do if the truck touches a power line?
Stay in the cab, warn others to stay away and call 911. Leave only if the truck is on fire or smoking: jump clear with both feet together, without touching the truck and the ground at the same time, then shuffle away at least 35 feet.
How far should a truck stay from a trench or excavation?
OSHA requires equipment that could fall or roll into an excavation to be kept at least 2 feet from the edge or held back by a retaining device. A loaded truck can cave in a trench wall from much farther back, so stay where the site’s competent person directs, and ask for barricades or stop logs when you cannot see the edge.
What class of safety vest should a truck driver wear?
On federal-aid highway jobs, workers exposed to traffic or construction equipment must wear ANSI/ISEA 107 Class 2 or Class 3 high-visibility apparel. Class 3 adds sleeves and more coverage and is recommended for night work. Follow the site’s rules, which may require more.
Do truck drivers have to wear PPE on construction sites?
Once you step out of the cab you are a worker on foot, so follow the site’s PPE rules. That usually means a hard hat, a high-visibility vest or shirt, safety-toe boots and safety glasses, plus gloves and hearing protection for the task.
Who pays for a truck driver’s PPE?
Under OSHA’s construction rule, employers must provide required PPE at no cost to employees. They do not have to pay for non-specialty safety-toe boots or prescription safety glasses that workers may wear off the job, or for everyday work clothes and weather gear. Owner-operators buy their own.
What is stop work authority on a construction site?
Stop work authority lets anyone on site, including subcontractors and delivery drivers, stop a task they believe is unsafe without being punished for it. It is a company or project policy, not a federal OSHA rule, so ask whether the site has one when you check in.
Can a truck driver refuse to enter an unsafe job site?
Often, yes. OSHA protects workers who refuse work that a reasonable person would see as an imminent danger of death or serious injury, after asking the employer to fix it, when there is no time to go through OSHA. The STAA also protects truck drivers who refuse to operate a truck when doing so would actually break a federal safety rule, or when the truck’s unsafe condition gives them a reasonable fear of serious injury and the employer will not fix it. This is general information, not legal advice.
