Quick answer: “I was just going with the flow of traffic” is not a legal defense to a Maryland speeding ticket. Maryland’s posted limits are absolute under Md. Code, Transp. § 21-801.1 — the fact that everyone around you was speeding does not make your speed lawful, and being singled out of a pack is not itself grounds for dismissal. What can help is challenging how the officer measured or identified your car, and using the surrounding conditions in mitigation.
I’m David Waranch, and I’ve handled thousands of Maryland speeding cases. “I was just keeping up with traffic” is one of the most common things drivers tell me, and I understand the instinct — highway traffic usually moves above the limit, and getting picked out of the crowd feels arbitrary. But the law does not work the way most people expect.
The myth: “Everyone else was speeding too, so the ticket isn’t fair.” Maryland speed limits are maximum lawful speeds, not averages or suggestions. Nothing in the traffic code makes your speed legal because other drivers were also over the limit, and no judge will dismiss a ticket on that basis. Do not build your case around it — build it around the measurement, the identification, and mitigation instead.
Why Doesn’t It Matter That Other Drivers Were Speeding?
Because Maryland uses an absolute speed-limit framework. Section 21-801.1 states that the posted limits “are maximum lawful speeds,” and that a driver “may not drive a vehicle on a highway at a speed that exceeds these limits.” Exceeding the number on the sign is the violation, full stop. The companion basic speed law, Transp. § 21-801, adds a duty to drive at a “reasonable and prudent” speed for conditions — which can make you unsafe even at or below the limit. Neither statute contains any exception for what the cars around you were doing.
The logic is simple. If “everyone else was speeding” were a defense, the limit would become whatever speed a group of drivers decided to drive that day. Courts across every absolute-limit state have rejected that argument, and a Maryland District Court judge has heard “I was just keeping up with traffic” hundreds of times. The variations fare no better: “another car passed me,” “I sped up to stay safe,” “the truck behind me was tailgating.” Those may explain why you were speeding. They do not excuse it.
When Does the Surrounding Traffic Actually Help?
Traffic conditions can matter — just not as the defense drivers imagine. They matter as facts supporting a different argument: whether the officer accurately identified and measured your specific vehicle. Here is the honest split between what “flow of traffic” cannot do and what the same underlying facts can do.
| What “flow of traffic” cannot do | What the same facts can do |
|---|---|
| Make your speed lawful because others were speeding | Show a radar reading may have captured a different car in a tight cluster |
| Force a dismissal because you were singled out | Undercut a pacing estimate when following distance kept changing in heavy traffic |
| Excuse being 30+ mph over the limit | Support a mitigation or PBJ argument that this was an isolated moment, not a pattern |
| Substitute for challenging the State’s evidence | Give a prosecutor a reason to reduce the charged speed |
In heavy traffic, a radar beam several hundred feet out can be tens of feet wide — wide enough to cover multiple lanes. The unit displays the strongest return, usually but not always the closest car, so the officer’s training is what pins the reading to one vehicle. When three or four similar cars are clustered together, that identification is fair game. This is where clustering has real legal weight — not as a “flow of traffic” defense, but as the factual backdrop for an identification challenge or a challenge to how radar speeding tickets work in Maryland. Pacing has the same weakness: it needs a steady following distance over a long enough stretch, and congested traffic routinely breaks that, as I explain in how pacing speeding tickets work.
How Does Traffic Context Help at Sentencing?
Even when the speed itself cannot be beaten, context shapes the outcome. A driver moving with surrounding traffic at a moderate excess reads very differently from one weaving alone at high speed on an empty road. That framing matters most for Probation Before Judgment under Md. Code, Crim. Proc. § 6-220, which lets a judge withhold the conviction so no points hit your record. The judge is weighing the risk that you will do it again. The argument is not “everyone was doing it, so don’t punish me.” The argument is “the conditions show this was an isolated incident, not a habit.”
Prosecutors weigh the same context when considering a reduction. A 15-mph-over ticket in bumper-to-bumper commuter traffic is often easier to knock down to a 9-mph-over ticket than the same speed at 2 a.m. on a bare highway. Fewer miles over means fewer points and a smaller fine — the penalties by speed range tie directly to how far over you were charged, so a reduction has real value even when a dismissal is off the table.
Does “Flow of Traffic” Help at 30+ MPH Over?
No — it helps even less. Under Transp. § 21-901.1(a), driving at least 30 mph above the posted limit is reckless driving, and following the Sergeant Patrick Kepp Act (effective October 1, 2025) that speed alone makes the charge automatic. Reckless driving is a must-appear offense carrying up to 60 days in jail, a fine up to $1,000, and 6 points. Courts and prosecutors treat 30-plus over as inherently dangerous no matter what surrounding traffic was doing, so “I was keeping up” carries no weight there. If that is your situation, read whether you’ll go to jail for reckless driving in Maryland before your court date.
What Should You Do If You Feel You Were Targeted Unfairly?
Do not argue “everyone else was speeding” at the roadside. It rarely changes the stop and often makes things worse — officers document a driver’s demeanor, and an argumentative driver can end up with citations that might otherwise have been warnings. Stay calm and, as soon as you can, write down the specifics for your case file: which lane you were in, how many cars were around you, where the officer was positioned, and the weather and visibility. If you believe the number on the citation is simply wrong, the measurement itself is the thing to attack — see what to do when your ticket lists the wrong speed and identification defenses when the officer stopped the wrong car. The roadside is not where you fight a ticket. The courtroom is.
When traffic conditions genuinely support a measurement challenge, the realistic outcomes are a reduced charge or a PBJ far more often than an outright dismissal. Dismissal happens when the State cannot prove the alleged speed with credible evidence, which is uncommon.

Bring the Real Facts, Not the “Flow of Traffic” Argument
The flow of traffic alone will not defeat a Maryland speeding ticket. But how the traffic was moving, how the officer measured the speed, and how your vehicle was identified can matter a great deal. A lawyer who examines the real evidence in your case can tell you whether a genuine defense or a strong mitigation argument exists. For a candid take on your odds, read why it’s so hard to beat a Maryland speeding ticket and whether you can fight one in court.
No. Maryland speed limits are absolute maximum lawful speeds under Transp. § 21-801.1. The fact that other drivers were also speeding does not make your speed lawful, and it is not grounds for dismissal.
Yes, but not as a flow-of-traffic defense. Heavy traffic and vehicle clustering can support a challenge to how the officer identified or measured your car with radar or pacing, and it can help at sentencing when arguing for a reduced charge or probation before judgment.
No. Driving at least 30 mph over the posted limit is automatically reckless driving under Transp. § 21-901.1(a) after the Sergeant Patrick Kepp Act. It is a must-appear charge with up to 60 days in jail, a $1,000 fine, and 6 points, and keeping up with traffic is no excuse.
