Understanding Traffic Signs 🛑

Purpose of Traffic Signs

Traffic signs in the United States are standardized by the Manual on Uniform Traffic Control Devices (MUTCD) and serve six primary functions:

• Regulatory Signs – Indicate laws that must be followed (e.g., Stop, Speed Limit, No U-Turn).
• Warning Signs – Alert drivers to potential hazards (e.g., Slippery Road, School Zone).
• Guide Signs – Provide navigation and distance information (e.g., Highway Exits, Route Markers).
• Construction & Maintenance Signs – Indicate road work, detours, and temporary conditions (e.g., Road Work Ahead, Lane Closed).
• Hearing Impaired Signs – Alert drivers to areas where individuals with hearing impairments may be present.
• Barricades & Channelizing Devices – Direct traffic safely around hazards or construction zones.

Key U.S. Traffic Laws and Rules

✅ Stop Signs & Right-of-Way

• Drivers must come to a complete stop at stop signs before proceeding.
• At four-way stops, the vehicle that arrives first goes first; if arriving simultaneously, the driver on the right has the right-of-way.

✅ Speed Limits

• Speed limits vary by state but generally follow:
  • Interstate highways (rural): 65-80 mph
  • Interstate highways (urban): 55-65 mph
  • Residential areas: 25-35 mph
  • School zones: 15-25 mph

✅ Yield & Right-of-Way Laws

• Yield signs require drivers to slow down and give right-of-way to other traffic before merging.
• Pedestrians always have the right-of-way at marked and unmarked crosswalks.

✅ Construction & Maintenance Signs

• Orange diamond-shaped signs warn of construction zones (e.g., Road Work Ahead, Lane Closed).
• Temporary speed limits are posted in work zones for safety.
• Flaggers & pilot cars may be present to control traffic flow.
• Fines double in work zones when workers are present.

✅ Hearing Impaired Signs

• Deaf Child Area signs are placed in residential areas where children with hearing impairments live.
• Hearing Impaired Pedestrian Signs alert drivers to potential pedestrians who may not hear approaching vehicles.

✅ Barricades & Channelizing Devices

• Barricades (Type I, II, III) are used to close roads or lanes.
• Drums and Cones guide traffic safely around hazards.
• Arrow Boards & Message Signs provide dynamic warnings and detours.

• Drivers must slow down to posted limits when school zones are active.
• No phone use is allowed in active school zones in many states.
