Count against rate
Britain's danger rankings usually count casualties, which rewards long, busy roads. The A38 is 1st by count of 1,710 ranked roads, and 1,116th by rate — below average once the 0.099 billion miles ridden on it are taken into account. See the full ranking.

Method and source
Motorcyclist casualties on this road from DfT STATS19, 2021-2025, divided by motorcycle traffic on the same road from the DfT annual average daily flow counts. KSI means killed or seriously injured. The interval is the 95% confidence interval on the rate; a rate is never shown without the miles it was divided by. We publish a page for a road only where that interval clears the national average of 2,170 KSI per billion vehicle miles, so roads that cannot be told apart from average have no page.
