Route 4 is a two-lane highway in most sections, with occasional four-lane stretches near towns. Road quality is generally excellent, with smooth asphalt and clear signage. Fuel stations are plentiful along the main highway, with major brands like PTT and Shell at intervals of 30–50 kilometers. Diesel prices hover around 30 baht per liter (as of 2024), and you can expect to spend about 1,200–1,500 baht on fuel for the entire trip, depending on your vehicle's efficiency.

Tolls are negligible on this route; you may encounter a few minor toll booths near the Songkhla end, but total fees are under 50 baht. Rest stops are frequent, with dedicated rest areas every 50–60 kilometers, offering bathrooms, food stalls, and sometimes petrol stations. Tips for smooth driving: carry cash for village markets, keep an eye out for occasional livestock crossings, and use GPS apps that include real-time traffic updates.

Road conditions are generally safe, but beware of monsoon rains causing slippery surfaces, especially on the west side. Always wear helmets if on a motorcycle and use headlights on overcast days. Speed limits are 90 km/h on highways and 50–60 km/h in towns; radar cameras are increasingly common. For families, consider stops at Khao Saming Animal Park in Trang or the Songkhla Zoo on the final day; both are well-signposted and child-friendly.

Pet-friendly options are limited but present: many large rest stops have open-air dining areas where pets are tolerated. Always keep your pet on a leash and carry water. To manage fatigue, take a break every 2 hours; recommended rest areas include the PTT station at Amphoe Thung Song (near Nakhon Si Thammarat) and the viewpoint at Ban Hat Samran in Phatthalung. For lunch, try a local diner near the highway that offers pad thai and som tam; prices are reasonable (40–60 baht per dish).

• Rest zones: Frequent; use PTT stations for clean facilities.
• Pet-friendly: Several roadside restaurants allow pets on patios.
• Safety: Check weather forecasts; avoid driving during heavy rain.

Just south of Phang Nga town, the road skirts Ao Phang Nga National Park, where limestone karsts punctuate the mangroves. A short detour to Khao Phing Kan, known as James Bond Island, is a classic stop for panoramic views, though you'll need a boat. Further south, Krabi's coastline offers stunning beaches and cliffs, but the drove bypasses popular spots like Railay; consider a side trip to Hat Tham Phra Nang for a swim.

The landscape transitions to rubber and oil palm plantations around Trang, punctuated by rolling hills and caves like Le Khao Kob. In Phatthalung, the plain opens up with rice fields and the eerie beauty of Thale Noi Waterbird Park, a freshwater wetland with over 200 bird species. As you approach Songkhla, the highway hugs the coast, offering glimpses of the Gulf of Thailand.
