Reaction time This allows us to move Time to initial steering (defined as the point at which the driver first began to use steering to avoid the crash) was 1.64 seconds on the IDS and 1.67 seconds on the test track. The latter is a road alignment visibility standard that provides motorists driving at or below the design speed an assured clear distance ahead (ACDA)[6] which exceeds a safety factor distance that would be required by a slightly or nearly negligent driver to stop under a worst likely case scenario: typically slippery conditions (deceleration 0.35g[7][Note 3]) and a slow responding driver (2.5 seconds).
