Final answer:
The maximum amount of driving hours permitted in a day for commercial drivers is 11 hours according to the Federal Motor Carrier Safety Administration (FMCSA) regulations in the United States.
Step-by-step explanation:
The maximum amount of driving hours permitted in a day depends on the specific regulations set by each country or state. However, in the context of commercial driving, the Federal Motor Carrier Safety Administration (FMCSA) in the United States sets maximum driving hour limits for commercial drivers. According to FMCSA regulations, commercial drivers are allowed to drive a maximum of 11 hours after 10 consecutive hours off duty.
In addition to the maximum driving hours, commercial drivers are also subject to other regulations, such as the 14-hour rule. This rule states that a driver may not drive beyond the 14th consecutive hour after coming on duty, following 10 hours off duty. Furthermore, drivers are required to take a 30-minute break after 8 consecutive hours of driving.
It's important to note that these regulations only apply to commercial driving and may vary by country or state. For non-commercial driving, there are generally no specific regulations on the maximum amount of driving hours permitted.
