ADAS camera CA20S

At 80 km/h a vehicle covers 22 metres in a single second. That is how long a glance at the mirror, the dashboard or the phone lasts — and that is how much room disappears before a foot even starts moving toward the brake. ADAS does not drive for the driver; it watches the road without pause and speaks up a second earlier.

What that looks like here shows up in the statistics. In Serbia in 2024, 177 crashes with a fatality involved only a single vehicle — the largest single group. A single-vehicle crash usually means leaving the lane or the road, with no other party that caused it. That is precisely the situation lane-departure warning responds to.

The cost of that second is not abstract. The national Road Safety Strategy puts the social cost of one crash with a fatality at €3.27 million. For a carrier it is not merely somebody else's statistic: there is the vehicle standing still, the driver lost, the dispute over fault, and an insurance premium that does not go back to what it was.

The European Union turned the same logic into law: new buses and trucks first registered in the EU from July 2024 must have lane-departure warning, emergency braking and blind-spot detection. That obligation does not cover vehicles already in a fleet — but the same technology can be retrofitted into them.
