Do I Need Insurance on a Broken-Down Car?
Research on whether a mechanically inoperable car still needs auto insurance — the registration-not-drivability rule in California, Texas, Florida, New York, and Nevada, Planned Nonoperation and Affidavit of Non-Use filings, UCC Article 9 lender insurance requirements and force-placed insurance for financed cars, why standard liability/collision/comprehensive coverage excludes mechanical breakdown, Mechanical Breakdown Insurance eligibility, FHWA secondary-crash data for roadside breakdowns, and New Hampshire's no-mandatory-insurance exception.
Is It Illegal to Hide a Car From Repossession?
Research on the criminal exposure of hiding a financed vehicle from a lender — UCC § 9-609 self-help repossession and the breach-of-peace limit, the mens rea line between passive default and active concealment, value-tiered "hindering a secured creditor" statutes in Texas, Ohio, Florida, California, and New York, Arizona's 2023 decriminalization under HB 2484, the Writ of Replevin and Writ of Bodily Attachment judicial remedies, and the Automated License Plate Recognition and skip-tracing technology that finds hidden collateral anyway.

Research on the legality of passing a garbage truck — the 1996 origin of Move Over laws, the NWRA/SWANA "Slow Down to Get Around" campaign now covering 30-plus states, the NY/CA/PA/OH/TX/VA/MD statute and penalty table, the double-yellow-line "obstruction" doctrine and Parker v. State, negligence per se and "right hook" civil liability, FMVSS 108 amber lighting and SAE J595/J845, FMCSA/CDL compliance and 49 CFR 393.95, ANSI Z245.1 vehicle safety design, Bureau of Labor Statistics occupational fatality-rate data, and the GAO-24-106216 public-awareness gap.
Is It Illegal to Have a License Plate in Your Window?
Research on windshield and dashboard license plate placement — the Texas Court of Criminal Appeals' Spence v. State ruling on the statutory definition of "front," the Montana Legislature's post-Lacasella rewrite of MCA § 61-3-301, California CVC §§ 5200-5201 fastening and height mandates, why ALPR infrared cameras cannot read a plate through glass, the crash-physics case against a dashboard plate as an airbag-deployment hazard, and FMVSS 108/SAE J686/J587 engineering standards behind exterior-only mounting.
Is It Illegal to Leave Kids in the Car?
Research on leaving a child unattended in a parked vehicle — the automotive greenhouse-effect physics behind a 117°F cabin on a mild 72°F day, why a child's core temperature climbs 3-5x faster than an adult's, the state "unattended child" statutes and their age/grace-period/supervisor-age variables, the strict-liability-versus-intent split, general child endangerment and manslaughter prosecution in states without a specific law (including Kentucky's Bryan's Law), Good Samaritan rescue immunity, "Forgotten Baby Syndrome" and the enforcement-disparity data behind it, and the federal rear-seat alert and seat belt reminder rulemakings.
