What is the safest speed on the highway?
Typically, the prevailing speed is what traffic engineers use to determine what the official speed limit should be on any given road. Speed limits are set using the speed of which 85\% of traffic flows. Studies show that this 85th percentile is the safest speed level.

What is a safe speed?
A safe speed is a speed less than the maximum at which the operator can take proper and effective action to avoid collision and stop within a distance appropriate to the prevailing circumstances and conditions.
What speeds are typically safe in the city?
The speed limit on city streets is usually 35 mph, though in residential areas and near schools, the limit is generally 25 mph.
What is the maximum speed limit on most highways?
Highway speed limits can range from an urban low of 25 mph (40 km/h) to a rural high of 85 mph (137 km/h). Speed limits are typically posted in increments of five miles per hour (8 km/h). Some states have lower limits for trucks, some also have night and/or minimum speed limits.
What is the speed limit on American highways?
What is the speed limit in the USA? The maximum speed limit on rural interstate highways is 70mph, with a 45mph minimum. On four-lane divided highways, the limit is 65mph, and on all other highways it’s 55mph. If you are driving through a designated school zone, you must drop to 15mph.

Which of the following is most important factor when determining a safe speed?
To determine a ‘safe speed’ for your boat, take into account the following factors: The visibility conditions (fog, mist, rain, darkness) The wind, water conditions and currents. Traffic density, type of vessels in the area and their proximity.
Why is safe speed important?
Speed limits help limit your speed, which in turn reduces the amount of time it takes for you to react to changes in the roadway or flow of traffic and makes it easier for you to stop your vehicle if needed.
How fast should the speed limit be on a highway?
The currently MUTCD states that the speed limit should be within 5 miles per hours (mph) plus or minus of the 85th percentile speed. The MUTCD does recognize that other road characteristics, such as alignment, parking practices, pedestrian activity, etc., are factors in setting safe speed limits.

How to determine the safest operating speed on the road?
However, there are other factors that may need to be considered when determining the safest operating speed. Some transportation professionals are also considering other approaches, such as expert systems, safe system, and possibly a 50th percentile data point for safe urban streets. Ideally, the operating speed should be close to the speed limit.
What is the FHWA method of setting speed limits?
The FHWA Methods and Practices for Setting Speed Limits: An Informational Report describes three approaches for setting speed limits. Engineering Approach – A two-step process where a base speed limit is set according to the 85th percentile speed, the design speed for the road, or other conditions.
