What is the maximum allowable slope for entry to a road access?

• A. 6 Degrees
• B. 8 Degrees
• C. 10 Degrees
• D. 12 Degrees

Answer: (B)

Fire department access must be able to accommodate large, heavily loaded vehicles, so there is a defined maximum slope at the point where entry to a road is made. If the grade is too steep, traction is reduced, stopping distance lengthens, and control becomes harder, especially on curves or when surfaces are wet or uneven. That upper limit is set to ensure a safe climb for apparatus and reliable access to emergencies. Among the given choices, the option that represents that established upper limit is the one that balances practical site terrain with safety for responding units—neither too gentle nor too steep. This is why it is chosen as the correct answer.
