The Rolling 24-Hour Rule

The Rolling 24-Hour Rule is not a separate limit.

It is how Working Time limits are measured.

Most drivers get caught because they think in:

• Calendar days

• Shift starts

• Midnight resets

The law does none of those.

The One Rule to Understand First

Working Time limits are assessed over a rolling 24-hour period, starting when your Working Time begins.

That 24-hour window:

• Moves forward continuously

• Does not reset at midnight

• Does not reset at shift change

• Does not reset when you change employer

What “Rolling” Actually Means

“Rolling” means the 24-hour window moves with you.

It always covers:

• The last 24 hours of time

Within that window, only Working Time is added up.

It is:

• Not “today”

• Not “yesterday”

• Not “this shift”

Every new minute worked pushes the window forward.

Why This Matters

Several Working Time Directive rules rely on this rolling window, including:

• Night work limits

• Total Working Time limits

• Combined work across jobs

If you misunderstand the rolling 24-hour rule, you will misunderstand everything built on top of it.

Simple Example

Scenario

• You start work at 18:00

• You continue working past midnight

• You finish later the next day

What happens

• Your rolling 24-hour period starts at 18:00

• It runs until 18:00 the following day

• All Working Time inside that window is added together

Midnight changes nothing.

Another Example (Early Start)

• You start work at 02:00

• You finish at 14:00

Your rolling 24-hour window is:

02:00 today → 02:00 tomorrow

All Working Time inside that window is assessed together.

It does not reset at:

• 06:00

• 09:00

• Midnight

High-Risk Example – Long Day, Short Turnaround (Critical)

Scenario

• You finish work at 18:00

• Total Working Time that day = 12 hours

• You take 9 hours rest

• You start your next shift at 03:00

What drivers often assume

“I’ve had my rest, so I’m starting a new day.”

❌ This is drivers’ hours thinking, not WTD thinking.

What the Rolling 24-Hour Rule actually does

• Your rolling 24-hour window is 18:00 (day one) → 18:00 (day two)

• When you start again at 03:00, you are still inside the same rolling 24 hours

• The 12 hours of Working Time from the previous day still count

• Any new Working Time is added on top

Why this matters

Even though your rest was legal, you may already be:

• At, or very close to, a Working Time limit

• At risk of a night work infringement if the shift crosses midnight

Rest compliance does not reset Working Time limits.

How This Links to Night Work (Important)

Night work is triggered if any Working Time occurs within the defined night period (commonly 00:00–04:00).

Once triggered:

• A 10-hour Working Time limit applies

• That limit is assessed over the rolling 24-hour period

This is why:

• Work done before midnight still counts

• Work done after midnight still counts

• Breaks do not reset the day

👉 Night work only makes sense because of the rolling 24-hour rule.

Breaks and the Rolling 24-Hour Rule

Breaks do one job only under the Working Time Directive.

They stop Working Time adding up.

That’s it.

When you are on a break:

• Working Time does not increase

• The Working Time counter pauses

But:

• The rolling 24-hour period does not stop

• The day does not reset

• Midnight changes nothing

Think of it like this:

• The 24-hour window keeps moving forward no matter what

• Breaks only decide whether minutes inside that window count as Working Time

A break helps by:

• Preventing extra Working Time being added

A break does not:

• Create a new 24-hour period

• Remove earlier Working Time

• Increase night work limits

This is why a driver can:

• Take all required breaks

• Still exceed a Working Time limit

Both things are assessed separately.

One-Line Memory Rule

Breaks pause Working Time — they do not pause time itself.

POA and the Rolling 24-Hour Rule

Periods of Availability (POA):

• Do not count as Working Time

• Do not reset the rolling 24-hour period

Once Working Time resumes, the same rolling window continues.

Second Jobs and the Rolling 24-Hour Rule

The rolling 24-hour rule follows the driver, not the job.

This means:

• Work for all employers is combined

• Changing company does not reset the clock

• Non-driving work still counts

Example

• Evening driving job

• Early-morning warehouse job

Both sit inside the same rolling 24-hour period.

Common Myths

❌ “It’s a new day”
❌ “Midnight resets it”
❌ “I changed shifts”
❌ “I changed employer”
❌ “I took a long break”

None of these reset the rolling 24-hour window.

How to Use This Safely

If your work:

• Crosses midnight

• Starts very early

• Involves long shifts

• Involves more than one job

Always ask yourself:

“What does my last 24 hours look like?”

That question prevents most infringements.

Key Reminder

The rolling 24-hour rule explains how limits are measured, not what the limits are.

You must still apply:

• Working Time definitions

• Break rules

• Night work rules

• Drivers’ hours rules

All systems apply at the same time.

Final Takeaway

The Rolling 24-Hour Rule:

• Does not care about dates

• Does not care about midnight

• Does not care about employers

It only cares about the last 24 hours of Working Time.

Understand this, and the rest of WTD falls into place.
