Operating a transport on Ontario highways is demanding. Heavy loads, tight timelines and unpredictable traffic all increase the risk that a commercial driver will be accused of following too closely under section 158 of the Highway Traffic Act (HTA). For someone who earns a living behind the wheel, a headway ticket is never just a small fine – it can affect your record, insurance, CVOR and employment.

For tractor-trailers and other commercial motor vehicles, the specific 60-metre rule in subsection 158(2) generally applies when the unit is travelling on a highway at more than 60 km/h. Understanding how that rule works – and how it interacts with the general “reasonable and prudent” test – is essential for anyone concerned about transport truck following distance.

As an experienced paralegal focused on Ontario traffic offences, I can say this with confidence: before you decide how to respond to any follow too closely charge, you should understand your rights, the law and how Traffic Paralegal Services can help.

What “Following Too Closely” Means for Transport Trucks in Ontario

Ontario’s Highway Traffic Act (HTA) uses a “reasonable and prudent” concept for general motorists, but commercial driving has an additional rule that can apply to transport operations at highway speeds.

In plain terms, the allegation is that your spacing behind the vehicle ahead was not enough given speed, traffic volume, and road conditions—especially when braking or stopping happens quickly. Police may form this opinion through roadside observation, pacing, or by reconstructing events after a collision (for example, by measuring impact points, skid evidence, or the position of trucks at rest). The “follow too close” set-fine offences are specifically listed under HTA s. 158 in Ontario Court of Justice set fine schedules (including a separate entry for commercial vehicles). 

Safe Following Distance for Trucks Under Ontario Traffic Laws

A safe distance in a transport context is not a single magic number in every situation. It’s a defensible buffer that accounts for:

  • the truck’s weight and load distribution
  • reaction time and line of sight
  • road friction (wet, snow, black ice)
  • grade changes, curves, and merge pressure
  • the behaviour of vehicles cutting in and out

That said, Ontario does impose a specific minimum headway rule for commercial vehicles in a defined circumstance (explained below). When that rule applies, it can override “rule of thumb” guidance like time-gap driving, because the threshold becomes a measurable minimum safe distance under statute.

Commercial Truck Following Rules: What the HTA Requires

Ontario’s law distinguishes between HTA s. 158(1) (“Follow too closely”) and HTA s. 158(2) (“Commercial vehicle — follow too closely”), which reflects that commercial operations face a separate headway standard in certain conditions.

For transport operations, the key legal concept is:

  • HTA s. 158(1): a driver must not follow more closely than is “reasonable and prudent” given speed, traffic, and highway conditions.
  • HTA s. 158(2): when a commercial motor vehicle is driving over 60 km/h, it must not follow within 60 metres of another motor vehicle (with an exception so this does not prevent overtaking/passing). This is commonly summarized in Ontario materials discussing commercial headway rules.

Importantly, the Ontario Court of Justice set fine schedule shows separate set fine entries for “Follow too closely 158(1)” and “Commercial vehicle — follow too closely 158(2),” including community safety zone versions.

Factors That Influence Safe Distance for Heavy Vehicles

Even where the “60 metres over 60 km/h” rule is in play, the safest approach is usually to leave more room than the minimum—because minimum legal compliance does not always equal operational safety.

Here are common factors that can turn a marginal gap into an allegation:

  • Load and braking performance: heavier loads increase stopping distance and reduce tolerance for sudden stopping.
  • Traffic turbulence: vehicles cutting in can compress your gap and trigger “accordion” braking.
  • Weather and visibility: spray, fog, darkness, and blowing snow reduce hazard recognition time.
  • Road geometry: crests, curves, and construction chutes shorten sightlines.
  • Vehicle ahead behaviour: inconsistent speeds, hard braking, or sudden lane changes.

Penalties for Tailgating or Following Too Closely in Ontario

A follow-too-close outcome can be more serious than many drivers expect—especially for commercial drivers whose record is tied to employability, dispatch eligibility, and carrier oversight. The Ontario Court of Justice set fine schedule lists set fines of $85 for “Follow too closely 158(1)” and $85 for “Commercial vehicle — follow too closely 158(2)” (with higher set fines in community safety zones). 

On top of the set fine, there are added amounts like court costs and the victim fine surcharge (which is why the “total payable” is usually higher than the set fine alone). Demerit points are typically 4 points upon conviction for following too closely, and novice drivers can face escalating sanctions (including a 30-day suspension) depending on licence class and circumstances.

Because many people search this topic as truck tailgating laws in Ontario, it’s worth saying clearly: the “ticket amount” is rarely the whole story. For commercial vehicles, the ticket also carries 5 CVOR points and may also affect commercial insurance underwriting, dispatch decisions, and carrier monitoring systems—especially if it is tied to a reportable collision.

Common Causes of Following-Too-Closely Accidents Involving Trucks

Following distance allegations often arise from a predictable set of real-world scenarios. Understanding them matters because defence strategy frequently turns on why the gap changed.

A few recurring patterns include:

  • Cut-ins and forced compression: passenger vehicles merge into the gap and immediately brake.
  • Sudden traffic wave: congestion causes a rapid “shockwave” of braking.
  • Downhill grade + load: gravity increases stopping distance and reduces margin.
  • Visibility limitations: spray/fog/darkness causes delayed hazard perception.
  • Distraction claims: after a crash, police may infer inattention based on impact and position—sometimes without direct evidence.

What to Do if You’re Charged With “Following Too Closely”

If you receive a ticket or summons, the goal is to protect your record early and build a clean evidentiary trail.

If you are a commercial driver charged with “following too closely”, paying the fine is never a good idea. These charges under section 158 are often difficult for the prosecution to prove, because they usually rely on an officer’s quick, visual estimate of speed, distance and spacing in dynamic traffic. Once you pay, you are convicted, the offence goes on your record and CVOR, and your options are gone. For most professional drivers, fighting the charge is the best option.

The Crown must still prove the case beyond a reasonable doubt. Proving that a heavy vehicle was within 60 metres, that speed truly exceeded 60 km/h, and that you were “following” rather than properly overtaking often leaves room for real doubt. There are defences and negotiation strategies available in many following too closely commercial vehicles matters.

A sensible plan looks like this:

  • Do not pay or plead guilty. Paying at the court office or online is the same as an admission of guilt and always harms a commercial driver in the long term.
  • Elect a trial and obtain disclosure. Use the options on the back of the ticket or the court website to get the officer’s notes, diagrams and any objective evidence.
  • Preserve your own evidence. Save dashcam footage, telematics/ELD data and write down details about traffic, weather, load and any sudden cut-ins or emergency braking.
  • Get help from Traffic Paralegal Services. We review the disclosure, assess weaknesses in the Crown’s case and pursue withdrawals, dismissals or reductions that better protect your licence, insurance and employment.

For a transport driver, a headway ticket is never “just a ticket.” Because the charge is often hard to prove and real defenses exist, contesting it is always the smartest decision for your career and long-term driving record.

When a Following-Distance Charge Becomes Careless Driving

A “follow too close” allegation can escalate into careless driving when police believe the conduct was a marked departure from safe driving, particularly where there is a serious collision risk, injuries, or aggravating driving behaviour.

Ontario’s set fine schedule lists “Careless driving 130(1)” with a set fine of $400 (and, in practice, the consequences can be much more significant than the set fine suggests, depending on the facts and whether a summons is issued).

The practical difference is that careless driving is treated as a more serious Highway Traffic Act offence, and it can have heavier downstream impacts on insurance and employment screening than a basic headway ticket.

How Legal Help Can Protect Truck Drivers Facing Traffic Offences

Commercial drivers often have more at stake than the average motorist: CVOR monitoring, carrier compliance, cross-border eligibility, and contract requirements can all turn on convictions and collisions recorded to a carrier profile. Ontario’s Commercial Vehicle Operator’s Safety Manual explains that CVOR abstracts track safety performance and can include detailed event data for collisions, convictions and inspections, and that convictions may be recorded with point values based on severity.

That is why early, focused representation matters: the right approach is not just “show up and hope,” but to analyze whether the Crown can actually prove the required elements, whether the officer’s distance estimate is reliable in real traffic, and whether objective data (dashcam/telematics) supports a safe-driving narrative.

If you want help built specifically around Ontario traffic court processes and commercial driving realities, you can speak with Traffic Paralegal Services about next steps, disclosure strategy, and resolution options.

Preventing Future Charges: Safe Driving Practices for Transport Trucks

Prevention is never just about avoiding a fine—it’s about reducing collision risk and avoiding record issues that can follow a driver for years.

Below are practical habits that help drivers maintain a safe distance without creating rolling roadblocks:

  • Use a consistent gap strategy: aim for a time-gap that naturally exceeds minimum spacing at higher speeds.
  • Anticipate cut-ins: expect cars to fill open space and plan gentle deceleration early.
  • Brake earlier, not harder: progressive braking reduces rear-end risk and stabilizes traffic behind you.
  • Improve visibility: keep windshield/defrosters optimized and manage spray in rain/snow.
  • Communicate with lane position: avoid sitting directly behind erratic vehicles when safe to reposition.

Many drivers search for safe following distance for trucks in Ontario because they want a simple rule. The most defensible approach is: comply with the HTA minimum where it applies, and leave extra room whenever conditions (weather, load, traffic) demand it.

FAQ

Usually by roadside observation/estimation, pacing, or crash-scene inference. Dashcam and telematics can challenge accuracy when traffic is changing quickly.

Yes. Visibility affects what’s “reasonable and prudent,” and can support why more spacing was needed (or why police claim it should have been even greater).

Letting the gap shrink after cut-ins, matching speed too closely in dense traffic, and underestimating downhill/loaded braking and stopping distance.

Use objective proof: dashcam video, telematics/ECM data (speed/brake timing), and notes/photos of road and traffic conditions.

Load weight, weather, road surface, traffic flow, visibility, and grade. For commercial vehicles over 60 km/h, HTA s. 158(2) can also set a 60-metre minimum (except while overtaking/passing).

Yes. They can show cut-ins, braking behaviour ahead, your speed control, and when you applied brakes.

Most often when it’s tied to a serious collision, injuries, or conduct police view as a marked departure from safe driving (e.g., careless driving).
