4′9″ = 57 in. Enter only the boxes you have. Delaware uses exit is tied to the booster manufacturer’s upper height or weight limit, not a fixed age or a 4′9″ line; the statute sets no age or numeric trigger, so a child stays in the booster until they outgrow it per the label (state guidance notes no booster has a height max under 4′4″).
The minimum law in Delaware: Your child has not reached Delaware's booster-exit threshold (exit is tied to the booster manufacturer’s upper height or weight limit, not a fixed age or a 4′9″ line; the statute sets no age or numeric trigger, so a child stays in the booster until they outgrow it per the label (state guidance notes no booster has a height max under 4′4″)), so a booster or child restraint is still required.
First-offense fine: No fine on a first offense; $25 on a later one. The 2024 amendment removed the first-offense fine, replacing it with a referral to the Office of Highway Safety for a free car-seat fitting. A second or subsequent violation is a $25 fine (plus court costs) for each violation.
Heads up: Delaware’s law changed effective June 30, 2024 (SB 68). It added codified rear-facing (under 2 and 30 lb) and harness (under 4 and 40 lb) stages, replaced the old "age 8 or 65 lb" booster line with the booster’s manufacturer limits, and removed the first-offense fine in favor of an education referral. Summaries citing "age 8 or 65 lb" describe the repealed pre-2024 version.

Plain-language summary, not legal advice.
This shows the minimum legal requirement in Delaware, not best safety practice, which is usually stricter, and not legal or safety advice. Always follow your car seat's manufacturer instructions. For the full four-stage rules, front-seat rule, and citation, see the Delaware car seat law reference, cited to 21 Del. C. §4803 (as amended by SB 68, 2024) (last reviewed 2026-07-11).
How Delaware car seat law works
Delaware overhauled 21 Del. C. §4803 effective June 30, 2024, and the widely copied "age 8 or 65 lb" booster rule is now out of date. The current law codifies the earlier stages: rear-facing for a child under 2 and under 30 lb, and a five-point harness for a child under 4 and under 40 lb, so orientation is real law here rather than best practice. The booster exit is the biggest change. Instead of a fixed age or weight, a child stays in a belt-positioning booster until they outgrow the manufacturer’s upper height or weight limit, then may use a seat belt before age 16. State guidance points out no booster has a height maximum below 4′4″, so most children stay boostered well into grade school. The front-seat rule is codified: no child 5′5″ or shorter and under 12 in front of an active passenger air bag. A first offense now brings a free fitting referral rather than a fine; a repeat offense is $25.
