Legal framework
The base law is the Motor Vehicles Act, 1988, Sections 91 and 92. Original provisions are decades old and the language is dated, but the substance is enforced. Key clauses:
- Maximum hours of work in any day: 8 hours, with overtime up to 10 hours total in exceptional circumstances.
- Maximum hours per week: 48 hours regular, extendable to 54 with rest compensation.
- Mandatory continuous rest: Half-hour after each 5 hours of driving.
- Weekly off: 24 consecutive hours per week.
State motor vehicle rules (notifications under Section 96) may impose stricter conditions for specific lanes — particularly hill states and on national highways at night.
Driving-hour caps in plain English
| Period | Maximum driving | Mandatory rest |
|---|---|---|
| Continuous (without break) | 5 hours | 30 min after each 5 hours |
| Single day (24h) | 8 hours regular / 10 hours max | 10 consecutive hours off duty |
| Single week | 48 hours regular / 54 max | 24 consecutive hours / week |
| Night driving block (21:00 - 05:00) | 4-5 hours continuous max recommended | 30 min after 3 hours, full rest at 5 hours |
The 21:00-05:00 night block has no separate hard legal cap, but most fleet insurance policies and customer SLA clauses treat it as a higher-risk window and impose stricter rest requirements.
Why night driving is the loaded gun
Three reasons night driving disproportionately produces accidents in India:
- Circadian fatigue. Human body has a natural sleep-pressure peak at 02:00-04:00. Reaction time at this window is measurably slower than at 14:00 even if you slept well.
- Visibility on Indian highways. Mixed traffic — bullock carts, parked broken-down trucks without reflectors, cyclists, livestock crossings. All harder to detect in the 100m headlight cone.
- Driver compounding. Indian long-haul drivers often drive day shifts too, picking up night shifts for overtime pay. Cumulative fatigue across multi-day trips compounds.
Insurance industry data: over 60% of fatal commercial vehicle accidents in India occur between 22:00 and 06:00, despite night traffic being a fraction of day traffic. Per-kilometre fatality rate is 4-7× higher at night.
The insurance angle most fleets miss
Standard commercial vehicle insurance policies have a clause requiring the driver to comply with the Motor Vehicles Act at the time of the incident. "Driving in excess of permitted hours" can be cited to deny or reduce a claim.
Real-world enforcement: insurers don't pull driving-hour records proactively. They only invoke this clause when:
- The accident is severe enough to trigger forensic investigation
- The police FIR mentions driver fatigue or hours
- The fleet's own GPS log is subpoenaed and shows violation
That last point matters. Your own fleet GPS data can be used against your insurance claim. If your software shows 11 hours of continuous driving and the truck rolled at the 11th hour, the insurer will see it. The defensive posture is to have the policy and enforcement in place so the data shows compliance, not violation.
"If the data exists, plan for it to be discovered." Don't hide GPS records. Use them to enforce policy, so when they're produced in a claim, they support you instead of sinking you.
A practical fleet policy that works
Tight legal compliance is one thing. Workable Indian highway operations are another. Here is a policy that balances both, used by tight-running 30-100 vehicle fleets:
- 5-hour continuous driving cap. Driver must halt 30 minutes minimum after each 5-hour leg. Halt under 15 minutes (toll, checkpoint) doesn't reset the clock.
- Night watch threshold: 3 hours. Between 21:00 and 06:00, continuous driving alert fires at 3 hours of unbroken motion. Driver gets a WhatsApp ping. Dispatcher gets the same ping. Conversation happens.
- Day cap: 10 hours / 24 hours. Any driver who has been driving 10+ hours of the previous 24 cannot start a new shift without a 10-hour off-duty period.
- Stop-frequency floor. On any 500+ km leg, at least 2 documented rest stops of 30+ minutes each. Less than that → review the trip before the next dispatch.
- Driver self-attest at trip start. Mobile app or WhatsApp form: "I had ≥7 hours of rest before this trip [Y/N]". Counterfeit-able but useful as a documented signal.
- Weekly off. 24 consecutive hours every 7 days, no exception.
The four alerts that catch fatigue before it becomes a claim
Alert 1 — Continuous driving threshold
3 hours during night block (21:00-06:00) or 5 hours during day block (06:00-21:00) without a 5-minute or longer stop. Stop floor of 5 minutes matters — Indian highway GPS noise from device parking can create false "stop" signals. Tune to 3 km/h.
Alert 2 — Stop-frequency violation
Trip distance > 400 km with fewer than 2 stops of 15+ minutes. Either the driver pushed through (fatigue risk) or your GPS is failing to detect breaks (signal issue worth checking).
Alert 3 — Cumulative daily hours
Sum of "in motion" time over rolling 24 hours exceeds 10 hours. This catches drivers who took multiple short breaks to game per-leg limits.
Alert 4 — Schedule conflict
Trip assignment given to a driver whose last trip ended < 10 hours ago. Caught at dispatch, not at the wheel.
Catch fatigue before the insurer does.
Traxium's Driver Safety module runs all four alerts out of the box — tuned for Indian highway noise floor (3 km/h GPS), with WhatsApp push to driver and dispatcher. 30 days free.

What is the legal driving hour limit for truck drivers in India?
Under the Motor Vehicles Act 1988 Section 91, regular maximum is 8 hours per day, extendable to 10 in exceptional circumstances. Weekly maximum is 48 hours regular, 54 max. Continuous driving capped at 5 hours before a mandatory 30-minute rest.
Is night driving legally restricted for commercial vehicles in India?
There is no blanket legal ban on night driving for commercial vehicles, but state notifications may restrict night movement on specific stretches (hill highways, ghat sections). Insurance policies typically treat 21:00-06:00 as higher-risk and may impose stricter rest requirements.
Can my insurer deny a claim if my driver exceeded driving hours?
Yes. Standard commercial vehicle policies include compliance with the Motor Vehicles Act as a claim condition. Severe accidents with documented hours-violation evidence (your own GPS log or police FIR) can result in denied or reduced settlement.
How long must a driver rest between two trips?
The legal minimum under Section 91 is implied through the 8-hour-per-24h cap. The practical fleet policy used by safety-tight operators is 10 consecutive hours off-duty between trips.
What is the best way to enforce driving hours across a fleet?
Automated alerts from your fleet management software, with WhatsApp push to both the driver and the dispatcher. Manual policy without alerts is forgotten by the second week.
