Accidents are up because fewer people on the roads inspire the existing drivers to speed more; fewer stops because there are fewer people on the road.

Nearly 160 more people died on Illinois roads last year than in 2019, making 2020 the deadliest year for Illinois drivers in 13 years, a surge officials say may have been fed by drivers speeding on roads left open by motorists who stayed home because of the COVID-19 pandemic.
About 1,166 people died in motor vehicle crashes in Illinois in 2020, a nearly 16% increase over 2019, according to the Illinois Department of Transportation. Thats a provisional number, said IDOT spokesperson Guy Tridgell, since it takes the state agency 12-18 months to finalize annual data.
Illinois traffic fatalities havent been that high since 2007, when 1,248 people died, according to recent and historic state data. Deaths include drivers, passengers, pedestrians, cyclists and motorcyclists.
State officials point to speeding and other risky driving behaviors, prompted by emptier-than-normal roads as states like Illinois issued coronavirus lockdown orders, as possibly feeding the jump in deaths.
