Ay, honestly, hindi na advisable na matagtag sa sasakyan by that point, mama! At 8 months, mas mabigat na ang baby at mas sensitive ang position mo, plus ang risk ng premature labor or placental issues ay mas mataas na. A few of my mum friends nag-avoid na talaga ng long drives or bumpy rides around that time, better to be safe, no? I'd really suggest checking with your OB about it, lalo na if sobrang matagal ang biyahe or kung sasakyan lang talaga ang paraan, para ma-advise ka nang tama based sa condition mo specifically.
