Question juridique clé
Whether the driver committed a serious traffic violation by following too closely.
Solution extraite
Yes. The following distance was insufficient to react safely to sudden braking, so the conduct amounted to a serious violation.
Motifs extraits
The Federal Court relied on ATF 131 IV 133 and held that a driver who cannot stop in time in case of unexpected braking breaches the minimum-distance rule; the SAN showed convincingly that the respondent would not have had time to react effectively.
