We wrote these practice questions from the facts in the New Hampshire Driver's Manual (New Hampshire Driver's Manual, New Hampshire Department of Safety, Division of Motor Vehicles; 52 PDF pages, the last page reads 'DSMV 360: Drivers Manual (Rev. 11/25)' (PDF metadata: created 2026-01-06, modified 2026-03-03; the file was served with Last-Modified 2026-03-03); linked as 'Driver's Manual (Operator), New Hampshire' on the DMV Forms page (https://www.dmv.nh.gov/forms), read 2026-11-10. The DMV site (dmv.nh.gov) refuses non-browser downloads (Akamai 403), so the PDF was fetched in the built-in browser and its text extracted. Page numbers cited are PDF pages; the printed page number is the PDF page minus 6 (printed p. 1 is PDF p. 7). The CDL, motorcycle and organ-donation material and the 'Test Your Knowledge' fill-in questions (PDF pp. 48-51, a study aid and not the exam) were not used as question sources. Statutes were read on gencourt.state.nh.us (RSA Title XXI, chapters 263, 264, 265, 265-A and 266) on 2026-11-10; several sections carry amendments effective 2026-07-01 (RSA 263:10) and 2027-01-01 (RSA 265:79-c fines, RSA 265:54 school bus penalties, RSA 265-A:14 refusal penalties and RSA 265-A:18), so no question tests those fine or penalty amounts. Handbook statements that differ from or go beyond current law and how they were handled: (1) railroad crossings (PDF p. 28 says buses that carry passengers and trucks carrying flammable or hazardous material must stop) is broader than RSA 265:50 (passengers for hire, school buses carrying children, explosives, flammable-liquid tank vehicles and LPG cylinders); only the school bus case, which both agree on, is tested; (2) speed limits (PDF p. 21 says '45 or 55 mph in other locations') omit that RSA 265:60 II(d) sets 45 mph only on unimproved rural highways and 55 mph elsewhere; questions use the statute; (3) child restraints (PDF p. 18) omit RSA 265:107-a I-c (passengers under 2 in a rear-facing seat); a question uses the statute; (4) school bus stops (PDF p. 33 says to stop at least 25 feet away 'in any direction' unless a physical barrier separates the roadway) is broader than RSA 265:54 III (only the other roadway of a divided highway with separate roadways, or a loading zone on a controlled-access highway); a question uses the statute; (5) the youth operator text (PDF pp. 11-12) predates the amendment of RSA 263:14 V (eff. 2026-01-01: a youth operator convicted of DWI, reckless driving or 30+ mph over the limit cannot be reissued a license for at least 90 days), which a question tests from the statute; (6) the manual gives no headlight-dimming distance, while RSA 265:114 says within approximately 150 feet, so dim_oncoming_ft and dim_following_ft use the statute; (7) the manual's following distance is four seconds (PDF pp. 22, 36) and the statute (RSA 265:25 I) sets no time, so following_seconds uses the manual; (8) the manual says New Hampshire has no mandatory insurance law (PDF p. 38); no section of RSA 264 read requires insurance in general, only proof of financial responsibility in cases such as RSA 264:2, 264:3 and 264:20, so questions follow the manual and common questions that assume compulsory insurance are excluded; (9) the REAL ID paragraph (PDF p. 11) still speaks of 7 May 2025 as a future date; not tested; (10) the new-resident 60-day rule (PDF p. 7) is stated only in the manual, not in a statute section read, and is tested from the manual; (11) the manual's work-zone sentence 'Fines may be doubled' (PDF p. 29) was not found in a statute section read and is not tested. Vision (20/40, 80% pass, 10-day retest), appointment and language facts come from the DMV page Driver Licensing Testing Requirements, read 2026-11-10; the youth-operator and practice-driving rules agree between the DMV pages, the manual and RSA 263:14 and 263:25. edition) and from official sources on road signs. Every answer links to its source, so you can check it and read more.
