2. Allow Extra Time: Give yourself additional minutes for slower travel speeds and potential congestion through work zones.
3. Obey Posted Signs & Crews: Remain alert and follow any temporary lane shifts or detours for everyone’s safety.

Stay updated by monitoring NJDOT alerts and local traffic reports for real-time conditions on Morris County roads. Use caution, observe reduced speed limits in construction zones, and remain mindful of roadside crews.
