Since when have hours of service regulations been in effect?

The hours of service regulations for commercial drivers were established to ensure safety on the roads by preventing driver fatigue. These regulations, which dictate the maximum amount of time a driver can operate a vehicle and the required rest periods, were introduced in the 1980s. This was a crucial decade for regulatory standards in the transportation sector, as growing concerns about traffic safety and the welfare of drivers prompted the implementation of these rules. The introduction of these regulations aimed to create a safer driving environment for both commercial drivers and the general public, contributing to a decline in accidents related to driver fatigue.

In understanding the context of this question, it’s important to note that while there may have been earlier discussions or guidelines regarding driving hours prior to the 1980s, the formal implementation of consistent regulations took place during this time. Hence, identifying the 1980s as the correct answer reflects the historical timeline of hours of service regulations being put into practice.
