Why are roundabouts safer than intersections?

Answer: Slower speeds and fewer conflicts

Slower speeds and fewer conflicts ✓ — Correct! Roundabouts are safer for two reasons: (1) They force slower speeds through curved paths (typically 15-25 mph vs 30-45 mph at intersections), reducing crash severity. (2) They eliminate dangerous conflict points—traditional intersections have 32 vehicle conflict points; roundabouts have only 8, and no head-on or high-speed T-bone collisions. Studies show 37% fewer overall crashes and 75% fewer injury crashes.

Roundabouts have more lanes — Wrong. Roundabouts don't necessarily have more lanes—many are single lane. Safety comes from two factors: (1) geometry forces slower speeds (15-25 mph through curves vs 30-45 mph through intersections), and (2) traffic flows in one direction with only 8 conflict points vs 32 at traditional intersections. This eliminates dangerous head-on and T-bone collisions.

Stop signs prevent all crashes — Wrong. Stop signs don't prevent crashes—drivers still run them. Roundabouts are safer because: (1) continuous yield flow (not stop-and-go) at slower speeds, (2) only 8 conflict points vs 32 at intersections, eliminating dangerous head-on and T-bone collisions, (3) slower crash speeds (15-25 mph) even if collisions occur. Studies show 37% fewer total crashes and 75% fewer injuries.
