Curves, fog and winter weather all demand lower speeds. Because of Georgia's usually mild climate, most Georgians have little experience driving in winter weather, so it's worth knowing how to prepare your car and handle ice and snow.

Know the rule

Curves are hazards, especially when roads are slick. Sharper curves are usually marked with an advisory speed sign, usually lower than the posted limit.

Know the rule

Slow down before entering a curve. If you're going too fast in it, don't brake forcefully (you may skid): lift off the accelerator, brake carefully and keep steering in your lane.

Handbook p. 40 ↗

If you must drive in heavy fog:

  • Reduce your speed
  • Slow down more when you see headlights or taillights; distances are hard to judge
  • Dim your headlights; bright lights glare in fog and make it harder to see
  • Don't drive with parking lights or hazard lights on
Handbook p. 39 ↗

Driving in winter weather:

  • Use chains or snow tires if you need extra traction; check the manuals first
  • Remove snow and ice from all windows before driving
  • Test your brakes gently to get a feel for the road; never brake suddenly
  • Slow down gradually before intersections, turns and stops
  • Keep a safe distance and reduce speed for conditions
  • Watch for hazards and changing road conditions ahead

Tips for safe winter driving:

  • Get your car serviced routinely; check the battery and cooling system
  • Fill the windshield washer reservoir; check wipers and defrosters
  • Verify floor mat installation to prevent pedal interference
  • Inspect your tires and check their age
  • Know your car, and plan your travel and route
  • Stock tools and supplies, and learn what to do in a winter emergency

Put it into practice

Fog rolls in on a rural road. Slow down, switch to low beams, and leave your hazard lights off. When taillights appear ahead, slow down even more.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

In heavy fog, why should you dim your headlights rather than use high beams?
  1. High beams create glare in fog
  2. Low beams reach farther in fog
  3. Dimmed lights are required by federal law in fog
  4. It is illegal to use high beams at any time

Answer: High beams create glare in fog

In heavy fog, bright lights create glare that makes visibility worse, so you should use dimmed headlights.

Handbook p. 39 ↗
What is one recommended step when preparing for winter driving conditions?
  1. Let some air out of the tires for traction
  2. Check the battery, coolant, and wipers
  3. Pump the brakes hard to test them
  4. Remove your floor mats to stop sliding

Answer: Check the battery, coolant, and wipers

Winter driving tips include checking your battery, cooling system, and windshield wipers/defrosters before winter weather arrives.

Handbook p. 40 ↗
On a curve, if you realize you are going too fast, what should you do?
  1. Forcefully apply the brakes immediately
  2. Ease off the gas, brake gently, stay in lane
  3. Accelerate through the curve to maintain control
  4. Turn the wheel sharply toward the outside of the curve

Answer: Ease off the gas, brake gently, stay in lane

Forcefully braking in a curve can cause a skid; instead ease off the accelerator and brake carefully while steering.

Handbook p. 40 ↗
Sharper curves are usually marked with an advisory speed sign showing a safe speed, often lower than the posted limit.
  1. True
  2. False

Answer: True

Advisory speed signs on sharp curves typically show a reduced safe speed, usually lower than the posted limit.
