Final answer:
The correct answer is option D.The regulations allow you 10 minutes to set out emergency warning devices.
Step-by-step explanation:
According to the given regulations, you have 10 minutes to set out emergency warning devices. This means that when an emergency situation arises, such as a car accident or a natural disaster, you are required to deploy warning devices within a 10-minute timeframe.
Having a clear and standardized time frame ensures that emergency responders can quickly respond to the situation and take appropriate action to ensure public safety.
According to Federal Motor Carrier Safety Regulations (FMCSR), specifically 49 CFR 392.22, a commercial driver must set out emergency warning devices within 10 minutes when stopped on the traveled portion of a highway or the shoulder of a highway for a reason other than necessary traffic stops. The regulations are established to ensure the safety of the driver and other road users by providing an early warning sign to approaching traffic. Emergency warning devices can include reflective triangles, flares, or other warning signals.
As an example of understanding time, consider these additional calculations:
15 minutes + 60 minutes = 75 minutes
10 minutes + 20 minutes = 30 minutes
15 seconds + 45 seconds = 60 seconds, which is equivalent to 1 minute
These exercises in time addition help solidify the concept of measuring time and converting units of time appropriately.
