If a speed limit is not posted before a curve on the highway, you should reduce your speed based on the road conditions, visibility, and the sharpness of the curve. Use your judgment to maintain a safe speed that allows for control of your vehicle. Additionally, be aware of other vehicles and adjust accordingly to ensure safety for yourself and others. Always prioritize caution in areas where speed limits are unclear.
Road conditions are slippery
Answer is radius = 1800/pi metres
This is not related to physics but to the driver's attention when approaching a curve. If the speed is kept the same, it's more difficult to control the vehicle specially if the driver is stressed, drunk, tired or sleepy. The probability of an accident would increase on this situation.
The curve in the road was thick with ice, causing many accidents on the highway.
Yes
ONLY when there's a wide shoulder or a parking lot, and the highway is straight and not near a curve straight ahead.
The majority of curves will begin with a warning sign and speed limit. Most importantly, slow your vehicle to the posted speed by braking before the curve. As you enter the curve, steer in the middle of your lane. Avoid hugging either sides. Half way into the curve, slowly begin to accelerate to move vehicle weight from the front to the rear which provides excellent handling and less front tire wear. Remember, prepare to control your speed before the curve, start to resume your speed half way into the curve.
No passing to the left should be done when you are approaching a crest or curve in the highway. A driver's view is obstructed during these times and passing would be dangerous.
if road conditions are bad and/or you are entering a blind curve
1) before starting down a hill 2) before entering a curve
You should begin to brake before you reach the sharp curve, ideally while you are still on the straight section of the road. This allows you to reduce your speed adequately and maintain control as you enter the curve. Braking too late, while in the curve, can lead to losing traction and possibly skidding. Always assess the curve's sharpness and road conditions to determine the appropriate speed before entering.
Its speed is 55 mph, and if the highway doesn't curve, then its acceleration is zero.
