3-day self-driving guide from Los Angeles to San Diego: April coastal highway traffic jam warning and alternative route recommendations

Analysis of traffic jams on coastal highways in April Spring is a popular season for self-driving travel in California. The temperature in April is pleasant and the number of tourists is relatively small compared to summer. However, coastal highways such as Route 5 or Route 1 may still experience congestion due to peak weekend travel, holidays or special events. As a rule of thumb: Watch out for peak times: 7:00am - 9:00am on weekdays (outbound to Los Angeles), 16:00 - 18:00pm (returning to San Diego), and all day on weekends. Congested Road Sections: Areas on Route 5 near Orange County and San Clemente are prone to congestion. It is recommended to travel off-peak or choose alternative routes. Alternative route suggestions: Avoid traffic and enjoy more scenery. Route 1: Inland Route 15. Start in Los Angeles and take Route 15 south. Although this route does not allow you to enjoy the sea view, the traffic volume is relatively small, making it suitable for tourists who pursue travel efficiency. On the way, you can make a detour to Temecula Wine Country for a wine tasting and a break. Route 2: Route 78 + Shoreline Bypass Avoid the San Clemente section of Route 5, turn west on Route 78, and connect to the Shoreline. Along the way, stop at the Carlsbad Flower Fields (in full bloom in April).

It is recommended to confirm the location of the connection point of the service provider (such as Thrifty, etc.) in advance to avoid confusion on site. Navigation Tools: Make it a priority to use Google Maps for real-time traffic information and set the "Avoid Tollbooths" option. Parking advice: Parking fees are high in downtown San Diego, so you can make full use of Uber/Lyft for short-distance transportation. Documents: Chinese driver's license + translation (car rental platform can assist with this). Sun protection products: sunglasses, high-magnification sunscreen (UV rays are stronger in California). Emergency items: portable charger, car phone holder, a small amount of cash (some parking lots only accept cash payments). Reminder: Don’t rush to remit money or pay a deposit before seeing the real thing to avoid being cheated. Travel agency-air tickets and ferry tickets related pictures
