you need to be a little more specific.
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.
A yellow speed limit sign is on designed as a cautionary measure. They inform the driver that a road condition(generally a curve or hill) is coming and that a recommended speed for safety is advised.
Road conditions are slippery
The maximum safe speed on a curve, indicated by a sign, is the speed at which a vehicle can safely navigate the curve under ideal conditions without losing traction or control. This speed takes into account factors such as the curve's radius, road surface, and potential weather conditions. It's important for drivers to adhere to this speed limit to ensure their safety and the safety of others on the road. Exceeding this speed can increase the risk of skidding or rolling over.
On many highways it is unsafe to continue at the normal speed limit as you go around a curve (especially for large trucks with a high center of gravity that might tip over), therefor reduced speed signs (often yellow advisory signs not the usual white legal signs) are posted indicating reasonable and safe speeds to use through the curve.
Regardless of the speed limit, there's always an accident on Dead Man's Curve, because bike riders and motorcyclists try to speed around the corner.
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.
Basically, an advisory speed limit sign is posted when there is an area of roadway where a hazard could occur. Example; a highway has a speed limit of 45mph. A curve that has a bridge directly on the other side may have a spped limit advisory of 35 mph. This limit is not, as some beleive, the maximum safe limit, but is the speed which gives the driver greatest chance of avoiding a problem if one occured with minimal impact on the traffic flow. These signs are not enforced as a speed limit sign, however, any time a driver is going too fast for conditions is illegal, regardless of what the speed limit sign or advisory exhibits.
To determine the proper speed for navigating a banked curve, you can use the formula ( v = \sqrt{r \cdot g \cdot \tan(\theta)} ), where ( r ) is the radius (50 m), ( g ) is the acceleration due to gravity (approximately 9.81 m/s²), and ( \theta ) is the banking angle (25 degrees). Plugging in the values, the proper speed is approximately 15.7 m/s. This speed allows for optimal cornering without relying on friction.

When another speed limit sign is reached that changes the limit from the previously posted one.
