How does time severity work in the Driver Safety Measurement System (DSMS)?
Answer
The violations in DSMS are impacted by time severity; that is, more recent violations
are weighted more heavily than older violations that occurred within the last year
count three times, violations that occurred between one and two years ago count
twice, and violations between two and three years old count only once.
