In almost every taxi fleet there's a driver who boasts about working fourteen hours straight. At first it looks like good news: more hours online means more trips served and more income for them and for the operation. But a tired driver drives worse, reacts more slowly, argues more with passengers and, sooner or later, has an accident or a serious complaint that costs far more than the extra trips they made.
The thesis of this article is that driver fatigue is an operational risk, not a personal matter for each driver, and that it can be managed with simple rules and with the data you already have from your trips. We'll look at why tiredness is so dangerous behind the wheel, how to spot it before it causes a problem, what limits on hours and breaks make sense, how to organise shifts so nobody depends on endless days, and how to talk about it with the fleet without it feeling like a punishment.
Why tiredness is an operational risk
Driving tired is very similar to driving after drinking: reflexes slow down, it's hard to keep attention on the road and microsleeps appear, those seconds when the driver closes their eyes without realising. At sixty kilometres per hour, three seconds of microsleep is fifty metres travelled with nobody watching the road. In a taxi, moreover, the driver isn't alone: they carry passengers who trusted your service.
Tiredness doesn't only cause accidents. It also shows in smaller things that harm the operation every day: the driver who takes the wrong route, the one who answers rudely, the one who turns down short trips because they've run out of patience, the one who misses an exit and lengthens the journey. Each of those details ends in a low rating, an argument over the fare or a passenger who never requests a trip again.
And the cost of a serious accident is paid by the whole operation: the vehicle off the road, insurance, paperwork, reputation in the city and, above all, the harm to people. That's why it isn't enough to say each driver knows when they're tired. Most tired people believe they can still drive well for a while longer.
Signs that a driver is working too much
You don't need to install cameras or special equipment to notice that someone is working too much. The trip history in your dashboard already tells you a lot, and some behavioural signs are easy to see if someone reviews them regularly. These are the most useful:
- Online sessions of more than ten or twelve hours almost every day.
- Few hours between the last trip at night and the first one the next day.
- Whole weeks without a single day off.
- Ratings that drop at the end of the shift rather than at the start.
- More complaints about manners or routes in the last hours of the day.
- Rejections or cancellations that pile up from a certain hour onwards.
None of these signs proves on its own that a driver is driving tired, but together they draw a pattern. What matters is reviewing them every week with the same criteria, for example in the weekly operations review, and not only when there's already been a problem. That way you can talk to the driver before the accident, not after.
What limits on hours and breaks to set
Every country and every municipality has its own rules on working hours and passenger transport, and the first step is knowing the ones that apply in your city. Beyond the law, it's worth the fleet having its own rules, clear and written, so nobody has to guess what is expected of them. Reasonable rules to start with could be:
- A maximum number of hours behind the wheel per day, agreed with the fleet.
- A break of at least fifteen or twenty minutes every few hours.
- A minimum number of rest hours between one day and the next.
- At least one full day off per week.
- No working day that combines the whole night and the following morning.
The exact figures depend on your city, the type of trips and what local regulation says, so there's no magic number. What does work everywhere is having few rules, easy to remember and applied equally to everyone. A rule that's only enforced with new drivers, and not with the regulars, protects nobody.
It's also worth deciding what happens when someone goes over the limit. At first a conversation and a reminder are enough. If it happens again, the fleet can ask them to log off that day or review their place in the busiest shifts. What matters is that the consequence is known in advance and isn't a surprise.
Organising shifts so nobody depends on endless days
Many drivers work too much because they feel it's the only way to reach what they need to earn. If you only set limits without improving income per hour, drivers will find a way to stay online longer, on your platform or another. That's why managing fatigue goes hand in hand with productivity: making each hour worked pay more so there's no need to work so many.
One way to achieve this is to concentrate drivers in the busiest hours instead of spreading them over long days with lots of dead time. If you know the demand pattern in your city well, you can build shorter shifts that match the morning, afternoon and weekend peaks. A driver who works eight well-placed hours can earn almost as much as one who spends twelve hours waiting for trips.
In fleets where two drivers share the same vehicle, a shared shift also helps: the car keeps working many hours a day, but each driver rests. The challenge is making the shift change punctual and making sure neither of them stretches their part at the other's expense.
We had drivers who stayed online from six in the morning until midnight. When we started reviewing hours every Monday and talking to them, we saw that many spent half the day waiting. We moved them to the busiest hours, they work fewer hours and earn hardly any less. Night-time complaints dropped quite a bit.
How to talk about it with the fleet
The biggest risk when setting rest rules is that drivers see them as a way of taking work away. To avoid that, the conversation has to start with their safety and their income, not with discipline. Explain that an accident can leave a driver without a car and without work for weeks, and that the fleet would rather they earn well in fewer hours than risk their health for a few more trips.
Listening before deciding helps a lot. Ask drivers why they work so many hours, which schedules suit them and what they would need to work less without losing income. Sometimes the answer is a debt, a rented car with a high fee or simply habit. Understanding the reason lets you adjust the rule or look for another solution, such as reviewing the vehicle fee.
Once agreed, communicate the rules in writing and through the channel the fleet uses every day, and repeat them in new driver training. Also recognise those who follow them and keep good ratings: the message is that taking care of yourself is part of being a good driver, not a sign that someone works too little.
Measuring whether the rules work
Rules only work if they're reviewed. Every month, compare the same indicators before and after introducing them: average hours online per driver, how many go over the limit, ratings and complaints at the end of the shift, incidents and completed trips. If hours drop and completed trips hold steady, you're on the right track. If trips fall a lot, perhaps the shifts don't match demand and need adjusting.
Also review drivers one by one, especially those who keep going over the limit. Behind a driver who can't manage to rest there's usually a problem that can be solved with a conversation, a change of schedule or an adjustment to how they work.
Rested drivers, a safer operation
Fatigue doesn't show up on a single day's dashboard, but it builds up week after week until it appears as an accident, a serious complaint or a good driver who leaves exhausted. Managing it doesn't require complicated technology: it's enough to look at the hours you already record, set a few clear rules, organise shifts around demand and talk to drivers as people whose safety matters.
Fleets that look after their drivers' rest don't work less: they work better. They have fewer accidents, more satisfied passengers and drivers who stay longer. Start this week by reviewing the hours of your ten most active drivers; you'll probably find there the first conversation worth having.
