Six in the evening. On the bridge over the lake the traffic slows. Here every crash ends up in the statistics.

00:12.419 --> 00:20.931
For alcohol there is a breath test. For speed there are measurements. For sleepiness, at the scene, nothing.

00:21.660 --> 00:30.277
What is left is observation: heavy eyelids, yawning, swerving. Signs, not measurements.

00:31.016 --> 00:39.111
So the Swiss figure is an estimate: on motorways, 7% of serious crashes, according to the BFU.

00:39.841 --> 00:46.130
What is not measured doesn't make it into the plans. And what is not in the plans is not prevented.

00:46.871 --> 00:51.516
Sleepiness is never counted. That is why it looks as if it isn't there.
