Compare six scoped references for ordinary trucks on Bangkok surface roads, named EXAT expressways, Lam Luk Ka Road Khlong 5–7, and four Phra Pradaeng sois. Read the vehicle class, road segment, Bangkok-time windows, exceptions and original source together. This is partial research, not legal advice or nationwide truck routing.
All windows use Bangkok time (UTC+7) and describe published prohibition periods. Outside these periods is not a route clearance. Holiday and permit checks remain manual.
Recorded catalogue review: 2026-10-07. Repeat online verification attempted 2026-10-07 was incomplete: the PRD guidance and EXAT order were accessible; the Lam Luk Ka police page, Samut Prakan order and linked DOH guidance could not be confirmed in this run. These references may be outdated. Confirm original orders and subsequent amendments before operational use. Partial research, not legal advice.

| Input or condition | How to interpret it |
|---|---|
| Named scope | The listed EXAT order covers named expressways and only Suksawat toll plaza–Thotsamarachan Bridge on the Rama III line. The Phra Pradaeng entry covers four sois, not all Samut Prakan. |
| Vehicle and exemptions | Ordinary six-wheel, ten-plus-wheel and trailer classes differ. Oil, dangerous goods, logs and piles require separate source checks. Permits are not validated here. |
| Source age | Publication and recorded review dates are visible per reference. A reviewed historical order may have later amendments; repeat online verification is incomplete and operational validation remains required. |
