Winter driving can be hazardous—check weather alerts. Emergency services: dial 911; roadside assistance via AAA or insurance app.

Emergency call boxes are present but less common; keep phone charged.

• Hazard areas: near Gary, IN (industrial traffic); intersection of US-20 and IL-84 near Galena (sharp curves).
• Speed limits: 70 mph on interstates, 55–65 mph on US-20.
• Recommended gas stations: Shell, BP, or Marathon (chain reliability). Avoid unbranded stations in Gary.
