Step-by-step explanation:
Permit holders can most reliably check where they're allowed to park by using technology such as mobile apps and online platforms. Many cities and universities now have dedicated apps or websites that provide real-time information about parking availability and permit restrictions. These platforms use GPS and other location-tracking technologies to help permit holders find designated parking areas and avoid restricted zones. Additionally, permit holders can also refer to physical signage and parking guides provided by the issuing authority to ensure they are parking in authorized areas.
